-------------------------------------+-------------------------------------
This patch was originally #16152, but was mistakenly removed in #20927.
This patch is still needed to build PPL in Cygwin (the patch just needed
to updated slightly for PPL 1.2).
A better patch would be to modify the autoconf files to not set
`PPL_CXX_SUPPORTS_ATTRIBUTE_WEAK` in the first place on Cygwin64--as it is
using `__attribute__((weak))` will compile fine, but fails to work
properly at link time. Not sure whether it's worth it though.
