Size of long in x64 Windows based binutils?

[Mayank Kumar]

On similar lines, I want to know if there is a 64 bit working implementation of binutils for interix. I mean has anybody tried to port or ported successfully a 64 bit implementation of binutils on Interix.

Thanks
Mayank

Hi Jerker,

It should be.

The configure file in the bfd/ directory should take of detecting if long long
can be used and the PE data structures are all defined in terms of a fixed
number of bytes.  (See include/coff/external.h).
