Does anyone know what this patch (stat32fix.patch) is doing??

The patch changes some files in the gimp source.
It changes the file information structure stat to _stat64i32
The structure holds some information for a file, e.g. last access, last modification, file size, etc.
The first suffix (32 or 64) defines the time size (32bit or 64 bit), the second suffix (after the i)
defines the integer size of the file size (32bit Integer/64 bit Integer).
The fix is not neccessary, but it is useful, when gimp is build for 64 bit.

Thank you.
