# 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
# and currently only case is Android: this is almost identical to arm-linux,
# but not quite. 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
#
# The setup of the platform variant is pushed relatively far down this
# file in order that we can inspect any of the variables set above.
# In the normal case ..
VGCONF_PLATVARIANT="vanilla"
# Android on ARM ?
