Apart from this Makefile hack, all I've done is to make dynamically
loaded code modules fail properly (as was already done for __mips__,
although I think this is too loose: I believe NetBSD for the pmax can
do dynamic linking), and to add test-and-set lock handling. As Bruce
suggested, this is done in a maximally efficient inlined way: I was
not aware that this code was so important, speed-wise.
The attached patches will allow postgreSQL to compile successfully on SCO
UNIXWARE 2.1.x. The patches fix the following problems:
1. Configure did not properly recognize the UNIXWARE system as needing the
univel port. It used the sys4 port.
2. Configure did not properly process the CC flag in the template file.
3. There was no working test and set locking implementation for the native
UNIXWARE compiler.
4. The test and set locking used for Intel X86 that was selected by defining
NEED_I386_TAS_ASM could fail in a multi-processor environment.
5. The makefiles for libpq and libpgtcl did not make a shared library for
the univel port.
Subject: [PORTS] minor fix for DGUX port
src/include/port/dgux.h needs the following three lines appended:
#ifndef BYTE_ORDER
#define BYTE_ORDER BIG_ENDIAN
#endif
I believe this to be correct for DG/UX on M88k processors. I don't have one of
the new Intel-based boxes to check on.
Subject: [PATCHES] port patch: ultrix4
ultrix4 doesn't compile without this. this also fixes a problem
with dynamic loading (ultrix relocatable objects must be loaded
with -G 0).
