It works, thanks. I used the (unmodified) genextern.sh and str.c from 1.0.3
and it compiles (and works!) fine now (BTW, I'm on a intel platform, so the
GNU 2.7.2 cpp is my one and only cpp, I checked it).
I only had problems with "make clean" ;-). The "xargs rm" should really be
"xargs -r rm" and "make clean" should also remove the Makefile to make it
clear that a fresh ./configure is needed.
After that only the "usual" compiler complaints showed up:
- missing "#include <wait.h>" in mmap_tests.c (since 1.0)
- sscanf in list.c with %u instead of %lu (since 1.0.2)
Ciao,
