Could you please verify this: I'm trying to get a version of some software running under Cygwin and I'm having real problems in finding routines that directly interface to the floating point processor rounding modes. I have code for different architectures that use fpu_control.h, ieeefp.h, fenv.h and WIN32 float.h. However, for various reasons, I need cygwin's runtime library environment and can't use the native Win32 port nor the mingw runtime. I keep seeing posts asking about fpu_control.h and answers saying it's not implemented for Cygwin. Then I see that ieeefp.h has prototypes declarations for fpsetround and friends but there is no library to link with (AFAICT). Is this correct, is there a way to do this under Cygwin or is Gary Polhill's library (announced http://sourceware.org/ml/cygwin/2004-06/msg00037.html) still the only way? Many thanks for any assistance.
