CDE has relied upon catgets() implementations following a relaxed
interpretation of the XPG internationalization standard that ignored
-1, the standard error value returned by catopen, as the catalog
argument. However, this same behavior causes segmentation faults with
the musl C library.
This patch:
- Centralizes (with the exception of ToolTalk) all calls to catopen(),
catgets(), and catclose() through MsgCat within the DtSvc library.
- Prevents calls to catgets() and catclose() that rely upon
undefined behavior.
- Eliminates a number of bespoke catgets() wrappers, including multiple
redundant caching implementations designed to work around a design
peculiarity in HP/UX.
- Eases building CDE without XPG internationalization support by providing
the appropriate macros.
Disable binding a privileged client port with rresvport() on Linux
systems using the musl C library, where that function is
unsupported. If there is a need for XPrint support, a BSD-licensed
implementation of rresvport() is available in the portable edition of
OpenSSH.
Shell isn't portable, so upstream ksh93 has a "flat" function that we can use
to put binaries in a static place that doesn't require a shell command. We still
do need an intermediate setup.sh shell script due to a bug in ksh that object
files aren't being put in lib, and FEATURE not in include. We also cut out some
unused symbols, and a hpux specific implementation of dynlib (new hpux should
conform to the posix implementation anyhow.)
We can reduce our differences from upstream ksh by simply using their
ERROR_translate() function instead of our janky and obsolete msg_translate,
we also move DtGetMessage() to msgs.c and lockedfiledescriptors and,
unlockfiledescriptors to extra.c to lessen modifications to init.c, which
all changes will hopefully be moved elsewhere in the future
This commit does three thing:
1. Sets appropriate bits on source files
2. Tells imake to build them as script files, not data files
3. Remove broken examples based on unused code
