It occurs to me that it might also be a good idea to put something like
this in timestamp.c:

    #ifdef __FAST_MATH__
    #error -ffast-math is known to break this code
    #endif

to guard against people modifying the CFLAGS after running configure.
The configure test is good, because it catches the problem sooner,
but it's not foolproof.

Comments?
