L.S.,
This STC fails to compile on Cygwin for x86_64:
// gcc -Wall -o stc-fenv stc-fenv.c
// Linux: gcc -Wall -o stc-fenv stc-fenv.c -lm
#define _GNU_SOURCE
#include <fenv.h>
int main()
{
fesetenv(FE_DFL_ENV);
fesetenv(FE_NOMASK_ENV);
}

However the STC does compile on x86.
Where has the machinery gone wrong?
File winsup/CVSChangeLogs.old/cygwin/ChangeLog.64 bit contains: (line
761 ff)
2013-02-08 Corinna Vinschen <cori...@vinschen.de>
* cygwin64.din (BASE): Set to 0x180040000.
(_fe_dfl_env): Remove useless symbol.
(_fe_nomask_env): Remove useless symbol.
File cygwin64.din does not exist anymore (as far as I can tell).
Has it been renamed x68_64.din?
Regards,
Henri
