Thanks for bringing up this issue which I've somehow managed to ignore
for a long time.  The example in the g77 manual is targeted for linux-gnu, 
and not as such applicable to Windows runtime. 

I'm going to write up the equivalent functions for Win32 API and post
that to the Mingw mailing list hopefully this weekend. The vendor (MS)
web site has more info on the solution if you search under 'floating 
point'.
