So I can take your version [*1*], drop this bit from the log: This seems to be caused by a change to the system headers which results in the _XOPEN_SOURCE macro now having prioity over the _GNU_SOURCE and _BSD_SOURCE macros (they are simply ignored). This in turn leads to the declarations of the above functions to be suppressed. and replace it with something like: <string.h> on Cygwin used to always declare the above functions, but a recent version of it no longer make them visible when _XOPEN_SOURCE is set (even if _GNU_SOURCE and _BSD_SOURCE is set). and keep the rest, I think. Thanks for digging this thoroughly.
