Here's a new one.

Tried all the variations, verified that split stack is still enabled and
uses gold linker for 64 bit targets
when using a 64 bit default compiler, and does not give the split stack
error for 32 bit default
compilers.


This is okay if Matthias confirms that it works.


yes, that fixes the build error.

using the preprocessor for this kind of check, you get wrong results for gcc-m32 on powerpc64, and for gcc -m64 on powerpc. The former looks like wrongcode, while the latter is just missed optimization. Not sure if it is worthfixing this.


I lost track of the x86 status. Is this now enabled there as well?
