Build Script Fix

This release fixes an oddity with the gfortran compiler on Windows. For some reason, the release builds using -O3 resulting in a segmentation fault; however, downgrading the aggressiveness of the optimization to a -O1 resulted in properly executing code. However, -O3 works as expected on Linux systems. Not exactly sure if this is a compiler bug, but a conditional statement has been placed in the build script checking to see if the code is being compiled on Windows, or anything else.
