                      2: 
                      3: Part 1. Compiling Gnu C in SCO Unix System V 3.2

                      5: 1. Rename stamp_extract.c to stamp-ext.c
                      6: 
                      7: 2. Change all occurrences of stamp-extract to stamp-ext in Makefile

                      9: 3. Remove all -g and -O options from the Makefile including the ones
                     10:    in gnulib and gnulib2 compiling rules.
                     11: 
                     12: (4. If needed use 'yacc' insteadt of 'bison' in BISON from Makefile.)

                     14: 5. Change all statements using 'ranlib' to use 'ar ts' insteadt.

                     16:    Old: if [ -f /usr/bin/ranlib -o -f /bin/ranlib ] ; then  ranlib gnulib ;fi
                     17:    New: ar ts gnulib
                     18: 
                     19: 6. Do not use libPW -library but use alloca.c from Gnu Emacs distribution.
                     20:    Uncomment 'ALLOCA = alloca.o' and make the following change to Makefile:
                     21:    Replace:
                     22:           alloca.o:    alloca.c
                     23:                $(CC) $(CFLAGS) -S `echo $(srcdir)/alloca.c | sed 's,^\./,,'`
                     24:                as alloca.s -o alloca.o
                     25:    With:
                     26:           alloca.o:    alloca.c
                     27:                $(CC) $(CFLAGS) -c $(srcdir)/alloca.c
                     28: 
                     29: 7. Run: config.gcc i386-sysv

                     33: 9. Rename explow.c, reload.c and recog.c to end with .gnu.
                     34: 
                     35: 10. In csh, run the following:
                     36:     foreach i (explow reload recog)
                     37:       ./cpp -P -I. -I./config <$i.gnu >$i.c
                     38:     end
                     39: 
                     40: 11. Run: make
                     41: 
                     42: This should produce a cc-compiled gcc, that is neither optimized nor
                     43: capable of optimization.
                     44:

                     52: 
                     53: This should produce an unoptimized gcc capable of optimization.
                     54: 
                     55: 16. Run: make stage1

                     57: 17. Run: make CC=stage1/gcc CFLAGS="-O -g -Bstage1/"
                     58: 
                     59: This should produce an optimized gcc capable of producing optimized and
                     60: debuggable code.
                     61:
