I can't reproduce this using GCC 2.8.1 for Solaris running on a
Solaris 2.6 machine.  The build steps that I used were:

mprep binary.tm -o binary.tm.c

gcc -c -I <path to mathlink.h> binary.tm.c

gcc -o binary -L <path to libML.a> binary.tm.o -lnsl -lsocket -lm -lML

Note the additional flags that link to the math and MathLink libraries
in the linking pass.

What release of GCC are you using?
