Pedantic preprocessor

[Sergei Gavrikov]

Hello list

They spoke what 'untested' GCC3.4.1 (arm-elf) generates more compact
code for float and double math than 'stable' GCC3.2.1 from ecoscentric
ftp. I use 'stable' GCC3.2.1 and build 'new' toolchain to test that.
That is (new code is a bit compact :). But, suddenly I found that the
GCC3.4.1 preprocessor is more pedantic then GCC3.2.1 one. I wonder
about CPP pedantism from other GCC suites (GCC3.4.X and GCC4.X.X). If a
described issue the below is the GCC's 3.4.1, please, forget this. If
other modern CPP cryes by a same way, a patch is attached.

MEDICINE

hal_arm.cdl describes 3 make rules to build arm.inc, vectors.o and
target.ld.  CPP 'sees' all $(CFLAGS) options and cryes about the
language specific flags. I found that it's enough to replace $(CFLASG)
by $(ACTUAL_CFLAGS), and all backs as it was with CPP from GCC3.2.1:

headers finished
build finished

I like to see these 2 lines together. And if anybody knows how to fix
this issue in platform CDL, please, enlight me.

Regards,

    Sergei
