Does libtoolize add -lgcc_s to postdeps? The above is > a stripped down link line that happens when I build the Open MPI trunk > using Intel 11.0 compilers.
postdeps are only expanded by 'libtool', but you posted a libtool command line that already included -lgcc_s, IOW, that particular argument was not added by libtool but in the Makefile already. You need to find out which Makefile macro set this, and since presumably the macro was @substituted@ by some configure script, find the configure code that set it. Otherwise I cannot say more.
