Brought to you by:

There is a mistake in the default TMAKEPATH. The code adds
/usr/lib//usr/lib/tmake-$TMAKE_VERSION/$gcc_platform but this should only be
/usr/lib/tmake-$TMAKE_VERSION/$gcc_platform
With this patch you don't nee to set a TMAKEPATH manually anymore, if you have the libs in the systems library location.
