What version of Bash do you have?  Version 2.03 and later comes with a
file config.site which, if installed in %DJDIR%/share, should take
care of all those problems automagically.

Anyway, if you got past the configure step, you may stop worrying
about this.

This says that kpathsea/lib.h has a prototype for the function
`basename', and that prototype is different from the one in the system
header unistd.h.

What should have happened was that the configure script should have
tested whether your library has a `basename' function, and if so,
refrain from using the replacement version of `basename' which comes
with Kpathsea.  This should work automatically if Kpathsea is
configured for the same version of DJGPP that you have installed.

I'm guessing that you installed kpseNNb.zip only, but didn't install
Kpathsea's sources.  In that case, what you are using is the version
of kpathsea/lib.h that was configured for DJGPP v2.01, where
`basename' was not available in the library.  That's why the prototype
of `basename' in kpathsea/lib.h is visible to the compiler, and that's
why you see this problem.

To solve this problem, I suggest to edit the file pdfdev.c, find the
line which says this:

 #include <unistd.h>

and replace this line with the following:

 #define basename djgpp_basename
 #include <unistd.h>
 #undef basename

(If this line is not in pdfdev.c, you will have to look for it in some
header file #include'd by pdfdev.c.)

Warning: this solution is a hack!  The *real* solution would be to
download the Kpathsea sources and reconfigure and rebuild it with
DJGPP v2.03.  However, I think what I suggest is worth trying, since
it is much easier and quicker.
