Building g++ fails

[NightStrike]

I can't build g++ anymore.  I get this during a make all:

../../../gcc/libgcc/../gcc/libgcov.c: In function '__gcov_execve':
../../../gcc/libgcc/../gcc/libgcov.c:948: warning: passing argument 2
of 'execve' from incompatible pointer type
../../../gcc/libgcc/../gcc/libgcov.c:948: warning: passing argument 3
of 'execve' from incompatible pointer type
configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
make[1]: *** [configure-target-libstdc++-v3] Error 1
make: *** [all] Error 2


Any ideas?
