Hi Vincent,
Unfortunately this is a fairly common problem.
If the flags were added by the user, they could set LIBS=-L/opt/gnu/lib
instead on some platfroms, but that won't work on HP-UX either because
its linker is rather strict that -L flags for paths that contain the
library be ordered before the -l flag for that library.
Anyway, the problem can be avoided by not putting the -L and -l flags
for gmp in LDFLAGS and LIBS, instead put both in e.g. GMP_LIBS,
(GMP_LIBS="-L/opt/gnu/lib -lgmp"), then add $(GMP_LIBS) to LDADD.
