# "internal compiler error: unspellable token PRAGMA"

# This regression has thus far only been seen on the GCC 4.7 compiler bundled
# with AOSP 4.3.0.  So this makefile, intended for in-tree kernel builds
# which are not known to be used with AOSP, is hardcoded to disable the
# workaround, i.e. set the define to 0.
