A note about MathMore.. even if we enable it.. we must have the GSL library installed and tell ROOT's config where it lives, otherwise Mathmore will not be built. Hence, MathMore has never been available in a GLAST ROOT build (actually it isn't even available in the windows binaries that ROOT-central supplies). See: http://root.cern.ch/cgi-bin/print_hit_bold.pl/root/roottalk/roottalk07/0343.html?mathmorevisual#first_hit
renamed cygwin's link.exe to link_cyg.exe:

Avoids cygwin's link app from interfering with the build
Run make
make
make cintdlls (which seems to do nothing)
make map (also seems to do nothing)
make install
