The following patch file can be used to compile up a version of GCC-2.0 CC 
running under SCO UNIX 3.2.2. I have not tried to compile C++ or OBJ-C

! Installing GNU CC on SCO System V 3.2
! =====================================
  
!    The compiler that comes with this system does not work properly with
! `-O'.  Therefore, you should redefine the Make variable `CCLIBFLAGS'
! not to use `-O'.
  
!    In addition, the compiler produces incorrect output when compiling
! parts of GNU CC; the resulting executable `cc1' does not work properly
! when it is used with `-O'.
  
!    Therefore, what you must do after building the first stage is use
! GNU CC to compile itself without optimization.  Here is how:
  
!      make -k cc1 CC="./gcc -B./"
  
!    You can think of this as "stage 1.1" of the installation process. 
! However, using this command has the effect of discarding the faulty
! stage 1 executable for `cc1' and replacing it with stage 1.1.  You can
! then proceed with `make stage1' and the rest of installation.
  
!    On Xenix, the same thing is necessary; in addition, you may have to
! remove `-g' from the options used with `cc', and you may have to
! simplify complicated statements in the sources of GNU CC to get them
! to compile.

! Installing GNU CC on SCO System V 3.2.2 
! ========================================
  
! 1. This info applies to the C-compiler only and not C++ or OBJ-C. At least you
!    are a fair way along the path if you can get the C-compiler built. Use the 
!    following line to configure under SCO:
  
! 	./configure sco
  
! 2. You will need to fix the '/usr/include/sys/signal.h' file. The problem 
!    line is the .ident clause on line 6. Just comment it out.
  
! 3. Then to create the initial c-compiler using rcc (NOTE: This generates a
!    lot of warning messages but their is nothing in the warnings that stops
!    the generated compiler working) do:
  
! 	make LANGUAGES=c 2>&1 | tee mklog
  
! 4. You can now proceed with `make stage1' and the rest of installation.

- ========= Checklist from of Ari Kautonen (akk@tut.fi) ======================
  
- Part 1. Compiling Gnu C in SCO Unix System V 3.2
  
! 1. Rename stamp_extract.c to stamp-ext.c
  
- 2. Change all occurrences of stamp-extract to stamp-ext in Makefile
  
! 3. Remove all -g and -O options from the Makefile including the ones
!    in libgcc1 and libgcc2 compiling rules.
  
- (4. If needed use 'yacc' instead of 'bison' in BISON from Makefile.)
- 
- 5. Change all statements using 'ranlib' to use 'ar ts' insteadt.
-    Example:
-    Old: if [ -f /usr/bin/ranlib -o -f /bin/ranlib ] ; then  ranlib libgcc.a ;fi
-    New: ar ts libgcc.a
- 
- 6. Do not use libPW -library but use alloca.c from Gnu Emacs distribution.
-    Uncomment 'ALLOCA = alloca.o' and make the following change to Makefile:
-    Replace:
- 	   alloca.o:	alloca.c
- 		$(CC) $(CFLAGS) -S `echo $(srcdir)/alloca.c | sed 's,^\./,,'`
- 		as alloca.s -o alloca.o
-    With:
- 	   alloca.o:	alloca.c
- 		$(CC) $(CFLAGS) -c $(srcdir)/alloca.c
- 
- 7. Run: config.gcc i386-sysv
- 
- 8. Run: make cpp
- 
- 9. Rename explow.c, reload.c and recog.c to end with .gnu.
- 
- 10. In csh, run the following:
-     foreach i (explow reload recog)
-       ./cpp -P -I. -I./config <$i.gnu >$i.c
-     end
- 
- 11. Run: make
- 
- This should produce a cc-compiled gcc, that is neither optimized nor
- capable of optimization.
- 
- 12. Run: make stage1
- 
- 13. Comment out the statement 'ALLOCA = alloca.o' from Makefile
- 
- 14. Rename files that end with .gnu to end with .c
- 
- 15. Run: make CC=stage1/gcc CFLAGS="-Bstage1/"
- 
- This should produce an unoptimized gcc capable of optimization.
- 
- 16. Run: make stage1
- 
- 17. Run: make CC=stage1/gcc CFLAGS="-O -g -Bstage1/"
- 
- This should produce an optimized gcc capable of producing optimized and
- debuggable code.
- 
- 18. Change installation options in Makefile and run 'make install'
- 
- That's it!  (I hope ;-))
