cross gcc 4.0.2 question

[Jan Capek]

Hi,

I am quite new to building gcc and resolving related issues. This is 
probably a general question regarding porting gcc. I have obtained gcc 
sources for PIC30 from Microchip but they seem to be broken/incomplete. 
When the xgcc attempts to build libgcc2.c module. It turns out that the 
xgcc is not able to compile a 'void function'(see the error below).

I am sure the problem is not trivial, but maybe could some one point me to 
what the machine definitions in case of any architecture should be 
checked? Or at least could someone confirm my theory that if the xgcc is 
not capable of doing a certain thing and emits a syntax error, it is due 
to some incompleteness in the machine definitions?

Please, CC me, since I am not subscribed to the list.

Best regards,

Jan Capek


The compiler error is below. The declaration that it dies on is a simple 
void function:
extern void *malloc (size_t);
