The below sample code will give a warning that visibility isn't
supported in this configuration. Either the GCC build is incorrect or
the sys/cdefs.h needs to be modified to define __hidden to empty.

gcc wiki demonstrates what needs to be done instead:
https://gcc.gnu.org/wiki/Visibility#line-76
at a minimum add `&& !define(__CYGWIN__)`; other posts also exclude
MinGW and ARM-PE (W10 Surface, IoT) targets using PE format not ELF;
gcc notes not all ELF targets support this:
https://gcc.gnu.org/onlinedocs/gcc-3.3.5/gcc/Function-Attributes.html#index-_0040code_007bvisibility_007d-attribute-1624
Which raises the interesting question - anyone tried porting Cygwin
to non-x86 arch?
