FWIW, I agree that this code does not look right.
The purpose of fesetenv(const fenv_t * envp) is to change the settings
of the floating point environment as specified by the parameter.
However, instead of using the values from the parameter, the current
code *overwrites* the passed in setting
Ahh, the wonders of google. I believe I have found the problem kai's

And, I believe I have found what the actual problem was. I don't think

Since mingw-w64 doesn't have any gfortran testsuites, I assume you want
me to run gcc's. Running "make -k check-f

OK, clear to apply to master, thanks for testing!
When I went to push, I had a problem with git that took me a while to
sort out. While I was doing that, I realized that this patch wasn't

According to 7.6.4.2 in c99, feho
Attached is an alternate fix. This does everything the previous patch

On the plus side it doesn't try to cram the SSE settings into the x87
settings. This not only makes things cleaner to code from the library
side, it makes things easier for users who actually want to
