[Python-Dev] autoheader warning for WITH_UNIVERSAL_NEWLINES

2002年4月16日 11:28:32 +0200

Martin,
how do I find out about all this autoconf magic? I simply used the code 
for another configure option (WITH_GC, I think) as a template and 
modified it for my needs. But I'm really groping in the dark with 
configure. I've have never heard of autoheader, for instance, and 
haven't a clue that I should have used it (if I should have, and for 
what:-)
