The code you've posted works for me (albeit it would've been probably easier/better
if you just had attached a tarball so that one wouldn't need to fiddle with
the (badly formatted) "code text").
It did compile with GCC 3.2.3 and GCC 3.4 (both directly downloaded from a GNU mirror;
i.e. no additional patches) and Redhat's GCC 2.96 on RH7.3 (installed from a RPM).
Either your distribution (it seems you're running a Slackware system and I don't have
any experience/knowledge about Slackware) has added a few patches and thereby
unfortunately some bugs creeped in OR (what I suspect) something else gets in the
way before the right header is included (you don't have by chance a file named "ctype.h"
lying around somewhere in your source dir?). OR it's something completely different...
You can just run your code trough the C pre processor:
g++ -E main.cc > main.ii
Then, have a look at the main.ii file.
Does it contain references to /usr/include/ctype.h? E.g:
# 1 "/usr/include/ctype.h" 1 3
If it does, is there some code which reads
extern int isalnum (int) throw ();
???
It should be there. Usually. ;-)
Maybe you can try upgrading your compiler? I mean, GCC 3.2.3 is already a bit
dated.
