Yeah, an asm volatile ("" : : "r" (x) : ) should please GCC and still be
portable to different platforms.
I thought using an asm () for each port to cause an exception specific

The discussion is becoming to technical for me.
Let me just say that adding --build=%m-apple-darwin`uname -r|cut -f1 -d.`
to config allowed me to build gcc without further glitch.
I guess it will do no harm to keep this addition even if it
becomes no longer necessary.
Thanks for the help

This seems horribly wrong somehow. Aren't we intested in the ${build}
-> ${host} compiler at this point anyway? So shouldn't we be testing
it? I think the whole block can go.
Hmm, it says indeed "this is going to change when we autoconfiscate".
Something like this?

Did I miss anything? What are the relative advantages of each

an exiting virtual machine be a good option? Except for Nice, this
option doesn't seem to be popular; there must be a catch.

I'm going to use an asm ().
Yeah, an asm volatile ("" : : "r" (x) : ) should please GCC and still be
portable to different platforms.
Paolo
if test ${build} != ${host}; then
some defaults
else
AC_PROG_CC
fi
AC_TRY_COMPILE
ac_objext is set at the expansion of AC_PROG_CC and if you take the if
branch, it never gets set.
Does anyone reading this know what the right thing to do is? Is there
anything in the autoconf documentation

Maybe you can use __builtin_trap() ?

Apparently it works.

You are right, the configure I am using since some time is:
ConfigureParams: --prefix=%p/lib/gcc4 --disable-multilib
--enable-languages=c,c++,fortran,objc,java
