Subject: [Rd] integer constants given by hexadecimal notation (PR#9648)

This works correctly on Linux.  The problem is that the author assumed 
that atof handles hexadecimal, which it does for a C99 compiler but not 
apparently on MinGW.

We have a workaround for this in mkFloat, and need to use that for the 'L' 
suffix case too.
