# - put AC_PROG_OBJC in a Darwin-specific part of this file

# Platform variants?

# Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
# But there are times where we need a bit more control. The motivating
# cases are Android and iOS. which are almost identical to arm-linux and x86-darwin,
# respectively. So this introduces the concept of platform variant tags,
# which get passed in the compile as -DVGPV_<arch>_<os>_<variant> along
# with the main -DVGP_<arch>_<os> definition.
#
# In almost all cases, the <variant> bit is "vanilla". But for Android
# it is "android" instead.
#
# Consequently (eg), plain arm-linux would build with
#
# -DVGP_arm_linux -DVGPV_arm_linux_vanilla
#
# whilst an Android build would have
#
# -DVGP_arm_linux -DVGPV_arm_linux_android
