Torbjörn: did you do so without *any* prior install of GMP, not 4.2,
not 4.1.x?  If there is a bug in locating libraries for "make check",
it is possible that you're testing against the installed gmp rather than
the newly-built one.

Note that libtool puts a shell wrapper around all executables in the
build tree.  When you execute them in the build tree, the script
fiddles with the link command to hard-code a path to the library
in the tree.  You should be able to see that the "real" executable
is linked properly using ldd:

        /lib/ld-linux.so.2 (0xb7fde000)
