Can you see if you can compile a simple C++ program that tries to
include <fenv.h>?  E.g.,

#include <fenv.h>

int main( int argc, char * argv [] )
{
    return 0;
}

And if you can do that, do you happen to have boost handy?
Cross-compilling it is a huge PITA, but in case you're already using
it...

One other random tidbit: I can't compile the above code as a regular C
program, either, which means that this might not be a C++-specific
issue...

Many thanks,
Tony
