Sure, via <cctype> (or, equivalently <ctype.h> in C).

Without more detail, it's impossible to tell. How did you configure it?
Are you using stock egcs-2.91.60, or are you using any of the patches
(eg., from my site)? Are you using a Cygwin release or a dev snapshot?
And what version?

Yes, I had the same problem.  It has something to do with differences
between the b20.1 December release and later snapshots.

I was building the Jan-15 newlib/winsup snapshot and egcs-1.1.1 OK
but then ran into undefined reference to _ctype blah blah when trying
to compile my stuff with the resulting tools.

I was also building the Dec Cygnus release and egcs-1.1.1 and then got
undefined reference to __imp_ctype blah blah when building my stuff.

I'm sorry that I can't give very good details but I do remember concluding
that it
was due to the newlib/winsup package somehow falling out of sync with the
egcs package.  I didn't trust my builds very much because I had to play
games
with links & headers, etc. to get both pieces to build.  I couldn't devote
any more
time to it and just cleaned out the whole mess and installed the
precompiled.

I'm pretty sure this will all be recreated by:

1. Installing full.exe

2. Installing the Jan-15 newlib/winsup src and egcs-1.1.1 src someplace.

3. Build both packages.

4. Install the resulting binaries over their older counterparts from
full.exe.

5. Try to build your own source.

Thank you! That's what I needed to know. Looks like we need to rebuild all
the object modules that uses ctype etc when using the new cygwin development 
snapshots. The interface for ctype was changed since b20.1, so it's
something that I don't see (I build everything with a stock b20.1 copy).

Unfortunately, I don't a simple workaround other than rebuilding the C++
runtime library in this case.

ps: I'm going to copy this to the cygwin list as well. Hopefully that's
not a problem.

It typically implies that some source module is using ctype *without*
including <ctype.h>. If someone can mail me the name of che module where
the undefined reference is coming from, I can take a look. Until then,
I'll simply ignore these messages just like I ignore hundreds of other
incomplete "bug reports" ;-)

This could be due to an oldver version of newlib which didn't export the
ctype symbols.

This is the life with snapshots. These are distributed so folks like us
can report and possibly fix problems. However, if we can't fix it, we 
also have to assume the responsibility of reporting these in a way that 
helps the maintainers to track it down.

I've built (patched, configured, bootstrapped in accordance with Mumit Khan's
instructions) egcs-1.1.1 and 1.1.2-pre1 and 2 on the Jan 23 snapshot binary
and got away from this problem.  The problem seems to occur when you have the
cygwin-b20.2 style snapshots installed along with a b20.1 version of the
compilers, where you're mixing the old and new implementations of ctype.
