Re: [png-mng-implement] MinGW build issues when srcdir != builddir

[John B. <joh...@gm...>]

​Yes.  I disabled the Ming/GW compiler warnings some time ago.

That one seems to be valid; it will falsely report a zero length file as
"read failed", as opposed to "zero length", obviating the fix I made in 1.7
on the platform you have (where size_t is bigger than unsigned long).

Hardly an issue for almost anyone, but annoying for sure.

I'll send a patch.
