Perl will probably not run on machines with a small address space.
AIX/RT may need a -a switch and -DCRIPPLED_CC.
AIX RS/6000 needs to use system malloc and avoid -O on eval.c and toke.c.
AIX RS/6000 needs -D_NO_PROTO.
- SUNOS 4.0.[12] needs #define fputs(str,fp) fprintf(fp,"%s",str) in perl.h
+ SUNOS 4.0.[12] needs -DFPUTS_BOTCH.
SUNOS 3.[45] should use the system malloc.
SGI machines may need -Ddouble="long float" and -O1.
Vax-based systems may need to hand assemble teval.s with a -J switch.
Ultrix on MIPS machines may need -DLANGUAGE_C.
Ultrix 4.0 on MIPS machines may need -Olimit 2900 or so.
Ultrix 3.[01] on MIPS needs to undefine WAITPID--the system call is busted.
+ MIPS machines need /bin before /bsd43/bin in PATH.
MIPS machines may need to undef d_volatile.
MIPS machines may need to turn off -O on cmd.c, perl.c and tperl.c.
Some MIPS machines may need to undefine CASTNEGFLOAT.
If you have GDBM available and want it instead of NDBM, say -DHAS_GDBM.
C's that don't try to restore registers on longjmp() may need -DJMPCLOBBER.
(Try this if you get random glitches.)
+ If you get duplicates upon linking for malloc et al, say -DHIDEMYMALLOC.
+ Turn on support for 64-bit integers (long longs) with -DQUAD.
5) make test
If possible, send in patches such that the patch program will apply them.
Context diffs are the best, then normal diffs. Don't send ed scripts--

Watch for perl patches in comp.lang.perl. Patches will generally be
in a form usable by the patch program. If you are just now bringing up
