Thank you for a great job! You even corrected os2/diff.configure!
Unfortunately, several sections of os2/diff.configure were erroneously
removed, so it will not create a valid config.sh any more (ar used
instead of $ar, and one extra method to extract symbols is not
tried). Unfortunately, I was away from my development machine, so
could not try it earlier.
A patch to correct this problem, and some other ones, follows.
a) Missing sections restored;
os2/diff.configure
b) my_flock added to os2/os2.c (libc contains a dummy
implementation only) (switchable off in case CRT DLL
is fixed in this respect);
os2/os2ish.h os2/Makefile.SHs os2/os2.c
c) depending on architecture, waitpid may be implemented or not.
New define HAS_WAITPID_RUNTIME is added and wait4pid
corrected correspondingly;
os2/os2ish.h util.c
d) if -S was given and the file name contained \ , it was
nevertheless searched on path;
perl.c
e) updated:
os2/Changes README.os2
f) by default use better gcc optimization options (as mbeattie
advices):
hints/os2.sh
[editor's note: this was applied in the reverse order to one a couple
of commits ago]
