Compiling gcc-1.37 and X11R4 with gcc under A/UX 2.0

[lamarche at ireq.hydro.qc.ca]

I was succesfull in recompiling X11R4 with gcc under A/UX 2.0 using the sources
I had since mars 1990 under A/UX 1.1. I had to use my old binaries of gcc to
recompile my new version of it under 2.0. I was unsuccesfull doing that with
the version provided at apple.com. Here are the few modifications that I made
to my sources.

******************************
*   gcc-1.37 for A/UX 1.1    *
******************************

Makefile:
< CFLAGS = -O -g $(XCFLAGS) -DAUX_ASM
---
> CFLAGS = -O -g $(XCFLAGS) -DAUX_ASM -DAUX2 -D_BSD_SOURCE -D_SYSV_SOURCE

********************************
*   X11R4 with the gcc         *
********************************
mit/config/Makefile.ini:
<          CFLAGS = $(BOOTSTRAPCFLAGS) $(CDEBUGFLAGS)
---
<          CFLAGS = $(BOOTSTRAPCFLAGS) $(CDEBUGFLAGS) -DAUX2 -D_SYSV_SOURCE -D_BSD_SOURCE

mit/config/macII.cf:
< #define OSName            A/UX 1.1
< #define OSMajorVersion    1
< #define OSMinorVersion    1
< #define BootstrapCFlags   -DmacII
< #define StandardDefines    -DmacII -DSYSV

> #define StandardCppDefines -DSYSV -D_SYSV_SOURCE -D_BSD_SOURCE -DAUX2

mit/config/site.def:
*** Ensure that HasGcc is defined
*** Modify
< #define CcCmd gcc -DNOSTDHDRS -fstrength-reduce -fpcc-struct-return -fwritable-strings \
<                   -traditional
---
> #define CcCmd gcc -DNOSTDHDRS -fstrength-reduce -fpcc-struct-return -fwritable-strings \
<                   -traditional -DAUX2 -D_SYSV_SOURCE -D_BSD_SOURCE
*** and
< #define CcCmd gcc -DNOSTDHDRS -fstrength-reduce -fpcc-struct-return
---
> #define CcCmd gcc -DNOSTDHDRS -fstrength-reduce -fpcc-struct-return -fwritable-strings \
>                   -DAUX2 -D_SYSV_SOURCE -D_BSD_SOURCE

I have tested most of the applications and the server and everything looks fine.

I hope this can help.
