Two questions to consider:
- What other effects would it have to define '_POSIX' ? In which other places
is this macro being referenced?
- Is it useful to have these signal names defined at all? If they can never
occur on native Windows, it does not necessarily make sense to define them.
Because then an application could not conditionalize like this:
#ifdef SIGFOO
... install signal handler for SIGFOO ...
#endif
Also consider the workarounds that Gnulib already does, in
doc/posix-headers/signal.texi .
