# This workaround is for what seems to be a compiler bug we observed in
# GCC 4.7 on AOSP 4.3.  The bug caused an intermittent failure compiling
# the "_Pragma" syntax, where an error message is returned:
#
# "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.
