That's putting it mildly. :-)

Seriously though, using automake/autoconf is less
evil than doing it all by hand, I can assure you.

"gen_errno.sh" is trying to pre-process <errno.h>,
so it can determine the real location of the
definitions (which may be in a file included by
<errno.h>, and not <errno.h> itself).  It does
this as follows:

    echo '#include <errno.h>' | COMPILER -E -

where "COMPILER" is all of the options from the third
onwards.  It appears that aCC does not understand "-"
to mean "take source from stdin" when pre-processing.

It will be limited to anything Unix-ish (don't even
bother using Visual C++ - it won't work and I have
no plans to make it work).  It should be possible
to get it compiling with aCC, once the GNU-isms in
the shell scripts have been fixed.

You may have to change the script to echo the line
"#include <errno.h>" to a temporary file first.  It
shouldn't be too hard to change, and I'll update my
version once you find something that works.
