Because Windows's pathnames are not case sensitive, to avoid include conflicts between our header file FEnv.h and the one from the C Standard library, <fenv.h>, the prior file was renamed. The motive for the relabel came to fix this include error in TestHelpers.cpp since a conflict arose with a file in the same directory when #include <fenv.h> was being used.
