It seems that you won the prize :-) I have patched Gen_fmgrtab.sh.in and
genbki.sh.in and executed configure again, and now it is compiling fine.

One "minor" problem is that I am getting many warnings complaining that
MAP_FILE is being redefined. Indeed, it is defined in
/usr/include/sys/mman.h (a system header file) for being used with mmap
and friends, and is redefined in include/libpq/hba.h. Since hba.h is
parsed after mmap.h and the preprocessor uses the last value seen
everything is allright, but I think that MAP_FILE should be renamed to
something like PG_MAP_FILE. Maybe it can wait for 6.4.1 or 6.5, but it
should be done.

I'll post a complete report if/when the build ends and (hopefully) the
regression tests are completed.
