Removed push/pop if there was no change to the warnings *in the same file* for a given compiler. This assumes the imported boost headers use a warning stack themselves. The pragmas don't seem to be required anymore, but were not removed to mantain compatibility with older versions of the boost library. Compiled with - clang version 6.0.1 (tags/RELEASE_601/final) - gcc (GCC) 8.1.1 20180531 against: - libboost 1.67.0-5
