Tell cmake to use c99 to fix build with GCC 15

Browse Source 
GCC 15 uses c23 instead of c17 by default. Apparently c23 is not backwards compatible to older C standards... This prevented me from easily compuling simh so I added a setting to tell cmake to use c99 fixing the compiling errors.

Fixes #490
