# This file is loaded by the tool init file (eg: unix.exp). It provides
# default definitions for gcc_start, etc. and other supporting cast members.
# These globals are used by gcc_start if no compiler arguments are provided.
# They are also used by the various testsuites to define the environment:
# where to find stdio.h, libc.a, etc.
# we want to use libgloss so we can get find_gcc.
