Well, I did this: $ nm libcygwin.a | grep isnan 00000000 T ___isnand 00000000 I __imp____isnand 00000000 T ___isnanf 00000000 I __imp____isnanf 00000000 I __imp___isnan 00000000 T __isnan 00000000 I __imp___isnanf 00000000 T __isnanf 00000000 I __imp__isnan 00000000 T _isnan 00000000 I __imp__isnanf 00000000 T _isnanf $ nm libm.a | grep isnan 00000000 T ___isnand 00000000 I __imp____isnand 00000000 T ___isnanf 00000000 I __imp____isnanf 00000000 I __imp__isnan 00000000 T _isnan 00000000 I __imp__isnanf 00000000 T _isnanf I don't see what would be wrong here. Do you have older libs from Cygwin in a path which might happen to be searched before the path with the real files? Did you try the --verbose optin to gcc?
