Hi,

On my powerpc mac with os x.4.10, building with apple's gcc 4.0.1 on the 
source of apple's gcc sources rev 5363 with gdc rev 127 and this patch, 
passing --disable-multilib to the configure script.

It fails to compile because in the file d/dmd/inline.c :
int AssocArrayLiteralExp::inlineCost(InlineCostState*),
int StructLiteralExp::inlineCost(InlineCostState*),
Expression* AssocArrayLiteralExp::doInline(InlineDoState*),
Expression* StructLiteralExp::doInline(InlineDoState*),
Expression* AssocArrayLiteralExp::inlineScan(InlineScanState*)
and Expression* StructLiteralExp::inlineScan(InlineScanState*)
were declared twice,
and there was another error about struct Statement not having a member 
function named "isIfStatement" that should have been used to avoid 
dynamic_cast, according to the comments.

I removed the duplicate methods and added isIfStatement, then the 
front-end is ok, but then when compiling libphobos I get :

../../../gcc-5363/libphobos/std/string.d:818: Error: identifier 'string' 
is not defined

Well, it's late, I'm going to sleep...
