chip@tct.uucp (Chip Salzenberg) (02/12/91)
The enclosed patches are a port of GCC 1.39 to SCO UNIX.
I appreciate RMS's addition of a SCO configuration file and other
patches to GCC 1.39. However, there were a few things overlooked
which are addressed herein, such as STRUCT_RETURN_CALLER_POP in
tm-i386sco.h. Also, RMS isn't going to add the Microsloth "#pragma
pack()" to mainstream GCC, so it is still a custom add-on. (GCC 2.0
will have a keyword to indicate packing, so all is not lost. :-))
NON-SCO USERS: You will be interested in the patch to stmt.c; it is
the GCC side of a G++ bug fix.
NON-SCO USERS OF SYSTEM V: You will want to use the patch to symout.c
to use getcwd() instead of getwd().
SCO USERS: At the end of the patches is a sharchive containing three
files you'll need to build GCC:
Makefile-sco A copy of my Makefile; uses "rcc" to compile GCC.
pragma.c Support for structure packing ("#pragma pack").
packtest.c Regression test for "#pragma pack".
Thanks again to Steve Bleazard for the original "#pragma pack"
support, done for a Xenix/386 port: he's a brave man. And, of course,
thanks to RMS for an excellent compiler.

This is a note for those of you who intend to use the GCC 1.39 patches I posted in the referenced article. The enclosed Makefile-sco file includes "getcwd.o" in the list of object files. If you have Doug Gwyn's getcwd() implementation, I suggest you install it as getcwd.c. If not, remove "getcwd.o" from the Makefile. We apologize for the inconvenience. [tm]
