On MacOSX

When building with threads I get

cpp error, trying with -no-precomp-cpp

When build without threads I don't

The command cc -DPERL_CORE -c -pipe -fno-common -DINT32_MIN_BROKEN 
-DINT64_MIN_BROKEN -fno-strict-aliasing -O3 -Wall miniperlmain.c

is issued in both cases, one results in mayham (threading), one does not.

The case seems to be that cppflags is NEVER passed to cc at all, but 
something that is only included when threading is on forces the cpp to 
go to "advanced" mode?

Infact from looking thru the makefile the cppflags seems to be totally 
ignored for anything else than makedepend and myconfig

I assume the correct fix is to properly pass ccpflags, is it interesting 
to find out why we suddenly start failing when threads are included?

Interesting to note that this also applies to MakeMaker since it doesn't 
pass cppflags to cc on darwin.
