Hi Will,

I've tried to use the anoncvs, but I need to know the required modules
to checkout, in addition to newlib and libgloss, as with those two, gcc
complains of missing files:

configure: error: cannot find install-sh, install.sh, or shtool in ..
"/home/davidfc/src/gcc-4.8.1/newlib"/..

Could you let me know what are they?. Usually I link the folders newlib
and libgloss from newlib released sources into gcc source folder, but
the cvs modules seem to have some things missing.

Regards.

David
