[PATCH] isnan: Add support for TinyCC

[Ludovic Courtès]

Hello,

The patch below adds support for TinyCC.  Without it, tcc bails out:

  isnan.c:132: division by zero in constant

Tested with tcc 0.9.25 on x86_64-linux-gnu.

Thanks,
Ludo’.

        * lib/isnan.c (FUNC): Treat TinyCC (`__TINYC__') like
        `__SUNPRO_C' & co.
