Yes, it's visible on -O1 and -O2.

It took me awhile to figure out that ~/.local/include/apbuild/ctype.h is being 
used in place of my system ctype.h.  If I comment out the optimization in 
that file, then it builds.  That's all well and good, but how should this be 
solved in Autopackage?

Now for the next trouble symbol...
  undefined reference to `__ctype_b@GLIBC_2.0'

The __ctype_b reference seems to come from stuff like isalnum(), and I can 
confirm it in my test program.  Unfortunately this one doesn't seem to be 
triggered by an optimization, so I don't know how to solve it.

FWIW, I'm on a 64-bit machine.  Maybe I don't have any glibc_2.0 stuff?
