# We use "=" here since using $(CPPFLAGS.master) is very tricky in our
# case - it MUST come as the last element but future changes in -D options
# may then cause silent breakage in the AST sources because the last -D
# option specified overrides previous -D options so we prefer the current
# way to explicitly list each single flag.
# Notes:
#   - "-D_BLD_DLL" comes from ${mam_cc_DLL} in Mamfile
#   - Be careful with "-D__OBSOLETE__=xxx". Make sure this is in sync with
#     upstream (see Mamfile) and do not change the |__OBSOLETE__| value
#     without examining the symbols that will be removed, and evaluating
#     whether that breaks compatibility with upstream binaries.
