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is obsolete on BSD; FreeBSD even throws an error if you include it with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strstream.h is now called "strstream" and is obsolete, but use it anyway until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.
Patch from Pascal Stumpf <Pascal.Stumpf@cubes.de>
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)
