For bit manipulations on pointers we do need integral type to hold it. In C99 it's declared as uintval_t. Unfortunately we have to support C89 which doesn't have such declaration. Solution is to provide own define.
Example of usage is in parrot/parrot.h:
* NOTE! UINTVAL is incorrect below. It should be UINTPTR or something like
* that. The equivalent of C99's uintptr_t- a non-pointer data type that can
* hold a pointer.
#define D2FPTR(x) UINTVAL2PTR(funcptr_t, PTR2UINTVAL(x))
#define F2DPTR(x) UINTVAL2PTR(void *, PTR2UINTVAL((funcptr_t) (x)))
my cleanup branch (pull request #704) makes ptrcast_t the Parrot-specific equivalent of uintptr_t
Add temporary fix for issue #378
Fix issue #378
There probably are more pointer to integer conversions which need to be fixed.
Pull Request #704 has been merged, close this issue.
