Introduce KORNSHELL make variable to point
to the implementation of the Korn Shell.
Use $(SHELL) or $(KORNSHELL) explicitly for
make programs that do not automatically call
shell scripts from the current directory.
dtksh can be now compiled on FreeBSD. Work in progress.
Needs a real Korn shell to bootstrap as $(KSHELL).
KSHELL is set by default to /usr/local/bin/ksh93
(generic POSIX shell may not work)
Tested on:
FreeBSD 9.0-BETA1 #0 r224912M amd64
Known issues:
xvmstat:
* sleep does not work well (SIGSTOP is delivered)
xpong:
* xpong: line 220: ball1x = max_x * 2.2 / 3 : arithmetic syntax error
* dtksh is rebuilt uncondtionally every time make is invoked
Fixes many, though not all 64bit-warnings. In lots of places, pointers are
cast to ints to be then used as array subscripts. The only way to deal with
this is to change them to long. Additionally, use calloc() to allocate the
int_array in istr.c and drop the (wrong) macro patch to istr.h. Should make
dtbuilder work on 32bit again.
This reverts commit 0d2f7866ac.
This causes great mayhem in building/generating dtbuilder .msg files
(corrupting them, and inserting '(nil)' all over the place).
These would cause dtbuilder, and any other program built by dtcodegen
to have screwed up colors, missing callbacks and other mayhem.
This was confirmed by others on the list - reverting this made those
issues go away.
It may be that the int -> long is correct, but the NULL check
certainly does not seem to do what was intended. I'll leave it up to
Pascal to investigate :)
This is a non-POSIX/ISO-C header. It is ok to include this on Linux, but it
is obsolete on BSD; FreeBSD even throws an error if you include it with
__STDC__ defined. Every system should nowadays have malloc() defined in
stdlib.h.
Diff is largely mechanical, replacing malloc.h with stdlib.h where it is not
yet included anyway.
strstream.h is now called "strstream" and is obsolete, but use it anyway until
all code is converted over. This also needs std:: added, at least for GCC
4.2.1. Lastly, when hardcoding the path to perl, /usr/bin/perl should be used
rather than anything else.
Mostly this is adding appropriate #includes and declarations,
but for WmImage.c we also change from using the proper name
for XmeGetMask, rather than the identical but renamed
version _DtGetMask which is not exported in any header.

The official POSIX name for this signal is SIGCHLD. Linux probably
has SIGCLD only for SysV compatibility, but BSD does not.
Patch from Pascal Stumpf <Pascal.Stumpf@cubes.de>:
So here are all the patches that deal with the fact that modern
compilers assume different scoping rules for variables declared in for
loops. On Linux, -fpermissive has been added as a compiler flag to
compensate for this old C code, but I think it is the wrong approach.
Sorry, couldn't help sneaking in a || defined(CSRG_BASED) and some casts
needed for other reasons ...

Most is just copied from the existing imake installation in
/usr/X11R6. Additionally:
* Allow overriding CDESharedRev, X11ProjectRoot and ProjectRoot
* Add a new define to be able to override MINCLUDESRC too
(this allows me to build CDE without symlinking any include directories)
don't use the idiom
char foo[BUFSIZ];
snprintf(foo, BUFSIZ, ....);
but
char foo[BUFSIZ];
snprintf(foo, sizeo foo, ....);
because this will automatically catch situations where the size of foo
is later changed, e.g. like foo[BUFSIZ + 8];
Fix another use of sprintf.
Patch from Robert Tomsick <robert+cde@tomsick.net>:
I believe this fixes vulnerability #3 from CERT CA-1999-11.[1] The other
uses of sprintf in DtAction seem to be safe.

Patch from Frederic Koehler <f.koehler427@gmail.com>:
These implicit definitions cause segfaults on x64 because
the implicit return type is a 32-bit signed int, rather than a pointer
type.
Patch from Frederic Koehler <f.koehler427@gmail.com>:
Define a final fallback for loading default window manager font;
before exiting, forcefully try to load "fixed" font. This is sufficient
to allow systems where fontList is set to an empty list to startup dtwm,
for now.
dtlogin's genauth routines were trying to open and read /dev/mem on
linux and (presumably) bsd systems in order to obtain random data used
in creating an auth key.
This is bad for a variety of reasons. Newer linux kernels (at least
on 3.2) issue the following warning to the kernel logs:
"Program dtlogin tried to access /dev/mem between 100000->102000."
Now on linux we will use /dev/urandom, and on CSRG_BASED (bsd) systems
we will use /dev/random to obtain some entropy.

I have a little patch for a problem that I found when I tried to
compile dthelp on 64bit FreeBSD. It could also be a problem on other
64bit systems. The problem is that the program context compiles but
fails running with segmentation fault.
context uses the function m_malloc() which is missing a correct
prototype sometimes. Then it's treated to return int instead of void *
. On 64bit systems this cuts off the higher 32 bits because void * is
64bit whereas int is only 32bit.
