ENH: determine typesize by compiling a file and reading strings from the compiled output.
Tested with various gcc, XCode, MSVC7, sdcc
For OSX when doing TRY_COMPILE() CMAKE_OSX_ARCHITECTURES is used, if there are different results an error is generated. CMAKE_OSX_ARCHITECTURES can be overwritten for the TRY_COMPILES with CMAKE_TRY_COMPILE_OSX_ARCHITECTURES.
