Yes, but we provide explicit -I and -L flags pointing to 4.3.2 (see
above; this comes from mpfr/release.nix.)

However, it may be that ./conftest above is picking /usr/lib/libgmp.so
at run time, presumably because /nix/store/...-gmp-4.3.2/lib is not in
the loader’s search path.  Nixpkgs’s ld-wrapper normally adds it to the
RPATH [0], but perhaps this has lower precedence than /usr/lib?
