Steve,

I went through this torment of not seeing  float.h when I first started
using gcc.  Then one day I noticed that a program was complaining
about conflicting with <float.h>  after much searching I finally found
it hiding in 

/ lib / gcc-lib / i686-pc-cygwin / 2.95.2 / include

I think that this is standard for gcc 
( substitute your machine type for i686-pc-cygwin
  and 2.95.2 for your version of gcc in the above )
and that you can just include <float.h> and it will be
automagically picked up.

I believe the rationale behind this is that float.h is very
compiler and machine specific and by doing it this way
gcc can support cross-compiling and native-compiling
on the same host :-)

Cheers
