# This is a bit of a hack.
# If we are compiling something with the bootstrapping compiler on
# cygwin, and it uses an include file from the rts (say), then we
# need to stop mkdependC from generating a dependincy on
#     c:/ghc/rts/include/Rts.h
# as that confuses make. So we use -isystem instead of -I, which stops
# these dependencies from being generated. Technically this is wrong if
# we depend on a library that is built inside the build tree, and we
# use headers from that library, but currently I don't think that's the
