According to 'man gcc':
-Wno-cpp (C, Objective-C, C++, Objective-C++ and Fortran only)
Suppress warning messages emitted by "#warning" directives.
So apparently on your system configure fails the test for a 64-bit
integer type because a #warning is emitted, and compiling with
-Wno-cpp gets rid of that (probably without breaking anything else).
The relevant portion of config.log seems to be this:
configure:13285: gcc -o conftest.exe -Wall -Wmissing-prototypes
-Wpointer-arith -Wdeclaration-after-statement -Wendif-labels
-Wmissing-format-attribute -Wformat-security -fno-strict-aliasing

I'm a little confused as to why -Wno-cpp fixes any of that, though.
