OK, I'll add that.

What exactly was the problem? Error messages?

If a header fails to compile after ctype.h has been included, we may
need to change the header.

These are defined in src/libes/vect32/georef/vars.c, which should be
part of libgeo. Were there any errors in building libgeo?

This is defined in src/libes/vect32/georef/geo_file.c, also part of
libgeo. However, I would expect this to generate an error; libraries
must come *after* any files which make use of them.
