Portability problems not fixed by Gnulib:

This function is missing on some platforms:
mingw.

POSIX does not specify whether @code{setjmp} saves the signal mask in the
@code{jmp_buf}.  It does on BSD platforms, and on glibc platforms when
@code{_BSD_SOURCE} is defined; in this case @code{setjmp} behaves like
@code{sigsetjmp}, and functions @code{_setjmp} and @code{_longjmp} are
available that don't save or restore the signal mask.  On System V platforms,
and on glibc platforms by default, @code{setjmp} doesn't save the signal mask.
