805	Undefined reference error upon building on Windows	MoC	fperrad	"When I try to build Parrot on Windows XP with MinGW GCC 4.4 + latest binutils, etc. and Perl 5.10, ''mingw32-make'' exits with undefined reference errors as stated in the attached error log.

After running Configure.pl include/parrot/config.h includes the following directives: 

{{{
#if defined(__cplusplus)
#[...]
#define PARROT_DYNEXT_EXPORT extern ""C"" __attribute__ ((visibility(""default"")))
#else
#[...]
#define PARROT_DYNEXT_EXPORT __attribute__ ((visibility(""default"")))
#endif
}}}

If I replace ''!__attribute!__ ((visibility(""default"")))'' with ''!__declspec(dllexport)'' it will compile just fine. ''mingw32-make smoke'' gives the following results: [http://smolder.plusthree.com/app/public_projects/report_details/24420]. ([http://gcc.gnu.org/wiki/Visibility] provides more information about this issue, though I'm still confused as it looks like those two statements should be equivalent?)

Since I'm almost a complete Parrot newbie I can't exactly tell if the 3 failures are related to my change as I don't know (yet) if the tests make use of any routines defined within ''dynlexpad.c''.
If I should provide more information please let me know, as said before I don't really comprehend Parrots structure yet and don't know wether there is a way to get more sufficient logs.
