L.S.,
This STC fails to compile on Cygwin for x86_64:

#define _GNU_SOURCE
#include <fenv.h>

However the STC does compile on x86.
Where has the machinery gone wrong?
The symbol export files were not correctly set up back then. I pushed
a
patch. New snapshots should be uploaded shortly to
https://cygwin.com/snapshots/
Thank you, Corinna!

(Cygwin: move FP environment exports to common.din)
Agreed!
(have not tested any snapshot yet; will do.)
