I must confess to ignorance of the reasoning for the separate "gnatgcc" for
building Ada, but even still from what I understand that build still has
REVERSE_CROSS=no. In my (admittedly brief) test, a native gnat build did
indeed correctly use "gnatgcc".
I also haven't had any luck making *any* bits of gnat or Ada work in a
REVERSE_CROSS=yes build anyways, so as far as I can tell that's a moot
point.
So if you are definitely seeing build failures with that patch I can only
suggest maybe rewriting it like this (with the "ifneq" rearranged as an
"ifeq" to make it more obvious what's going on).
ifeq ($(REVERSE_CROSS),yes)
CC = $(DEB_HOST_GNU_TYPE)-$(if $(filter yes,$(with_ada)),gnatgcc,gcc)
else
CC = $(if $(filter yes,$(with_ada)),gnatgcc,gcc)
endif
But even with that change I still can't cross-compile the gnat bits.
Cheers,
