# new stuff below, not yet turned on
#----------------------------------------------------------------
# Note: Tcl, expect, and dejagnu are only needed for running gcc's 
# regression tests.  The standard version of expect has a bug that
# causes spurious test failures, so we have to build our own.
# The spurious test failures are 
# described by http://gcc.gnu.org/PR12096, and are
# fixed by patches/expect-5.39/pr12096.patch
# A few example failures this fixes:
# FAIL: gcc.dg/cpp/tr-warn3.c 
# FAIL: gcc.dg/format/c90-printf-1.c 
# FAIL: gcc.dg/format/c99-printf-1.c
# FAIL: gcc.dg/format/ext-1.c
# I haven't modified crosstest.sh to use this version of expect/dejagnu,
# and tcl/expect/dejagnu take FOREVER to build and install on cygwin,
# so comment out the rest of this for now.
