[Qemu-devel] [PATCH] gcc detection fix for Mac OS X

Hello,

on Mac OS X the command 'which' always returns true - regardless of  
the result. This is a problem, when the configure script tries to  
detect the right gcc version. An alternative to 'which' could be to  
try to invoke the compiler directly.

Please have a look at the attached patch.


Thanks,

Jo.
