On HPUX 10.20:

make[2]: Entering directory `/home/tgl/pgsql/bsd-gettext-0.0/libintl'
/bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I..     -g -O2 -c gettext.c

gettext.c: In function `unmapit':
gettext.c:442: `MAP_FAILED' undeclared (first use in this function)
make[2]: *** [gettext.lo] Error 1

The HPUX man page for mmap documents its failure return value as "-1",
so I hacked around this with

#ifndef MAP_FAILED
#define MAP_FAILED ((void *) (-1))
#endif

whereupon it built and passed the simple self-test you suggested.
However, I think it's pretty foolish to depend on mmap for such
little reason as this code does.  I suggest ripping out the mmap
usage and just reading the file with good old read(2).
