# Nb: the AM_CPPFLAGS_* values are suitable for building tools and auxprogs.
# For building the core, coregrind/Makefile.am files add some extra things.
#
# Also: in newer versions of automake (1.10 onwards?) asm files ending with
# '.S' are considered "pre-processed" (as opposed to those ending in '.s')
# and so the CPPFLAGS are passed to the assembler.  But this is not true for
# older automakes (e.g. 1.8.5, 1.9.6), sigh.  So we include
# AM_CPPFLAGS_<PLATFORM> in each AM_CCASFLAGS_<PLATFORM> variable.  This
# means some of the flags are duplicated on systems with newer versions of
# automake, but this does not really matter and seems hard to avoid.
