It's not a question of header files. You have to force the linker to include the floating point stuff. IIRC there is/was an external "_fltused" which has to be referenced in the source. I also remember with MS VC 1.5, it was sufficient to declare a initialized global floating point variable somewhere, the reference to _fltused was not needed then.
