Thanks, I'm aware of that, but doing it in that way will also override any '*FLAGS += something' in the Makefiles, which might not always be good. Either we should implement my suggestions or have 'EXTRA_CFLAGS' (etc.) to be used for user customisations in the Makefiles.
When using make CFLAGS=something that is the behavour I want. Being able to set CFLAGS and not have the Makefile override what I set.
Though I do agree an extra cflags variable would be nice in some cases. One problem is HOST_CC and CC using the same CFLAGS.
make CC=gcc-3.4.2 CLFAGS="-O2 -mtune=athlon-xp"The Makefile will set HOST_CC to gcc which is 3.3.5 on my system. Gcc 3.3.5 does not accept the mtune flag so the make fails when building dyngen with HOST_CC. Though a simple work around is to also set HOST_CC so the native gcc is not used which does defeat the purpose of having HOST_CC and CC.
