Problems compiling a2ps for cygwin - workaround

[David_Hudson]

In the 4.13 series (all versions), the \lib\path-concat.c file has the
following lines:

#ifndef HAVE_MEMPCPY
# define mempcpy(D, S, N) ((void *) ((char *) memcpy (D, S, N) + (N)))
#endif

This causes an error during compilation.

As a quick workaround I changed the problematic lines to:
#ifndef HAVE_MEMPCPY
# define mempcpy(D, S, N) memcpy (D, S, N)
#endif

I realize this is a hack. I hope to look at this more closely and find a
better solution. In the meantime, a2ps 4.13b now compiles and appears to
work fine under cygwin. Note that the 4.12 version compiles fine
out-of-the-box.

Anyone know a better workaround? I am interested in getting a2ps included
in the cygwin distribution so it would be good to get this fixed.

Thanks
