I just checked out SVN today and I'm also getting undefined symbols at link 
time, e.g.: undefined reference to `__ctype_toupper@GLIBC_2.0'

I'm getting this both with Qt and OpenSSL (after futzing with their build 
systems to use apgcc/apg++, of course).  I'm using Ubuntu 8.04.

I haven't figured out exactly what compile or linker flags are causing this, 
as if I make a test program that includes ctype.h and calls toupper(), and 
compile and link with apgcc, it works.
