Fix sporadic floating point value comparison error.

I wonder why this did not appear earlier. I found this issue only
when compiling with Cygwin under certain circumstances. Error was:

  Generating tabs.cxx and header from tabs.fl...
  tabs.fl:2: unknown version '1.0303'

although fluid was the one linked under FLTK 1.3.3 in the build process.
The fix is to adjust FL_VERSION by a delta value of 0.00001.
