Description

I'm getting errors in gtest-port.h. Have tried various flags none are working.

Have searched and found similar errors, but no definitive solutions.

Any help is appreciated.

Thanks!

Research direction
Investigate the use of fileno, strdup, and fdopen in gtest port.h. These functions are POSIX and may require defining POSIX C SOURCE or including <unistd.h> on Cygwin. Check the #ifdef conditions around these functions (likely around line 2340). The user also has a compilation error in aggregate test.hpp which is unrelated to Google Test's code. Focus on resolving the missing declarations by adding the appropriate includes or macros for Cygwin.
