Document abort() bugs.
* doc/posix-functions/abort.texi (abort): Mention anomalies.
* doc/posix-functions/setjmp.texi (setjmp): Mingw has setjmp.
* doc/posix-functions/sigsetjmp.texi (sigsetjmp): Cygwin has
sigsetjmp.
* doc/posix-functions/siglongjmp.texi (siglongjmp): Cygwin has
siglongjmp, but only as a macro.
* doc/posix-functions/_longjmp.texi (_longjmp): Mention that this
is obsolete.
* doc/posix-functions/_setjmp.texi (_setjmp): Likewise.

@node setjmp @section @code{setjmp} @findex setjmp POSIX specification: @url{http://www.opengroup.org/susv3xsh/setjmp.html} Gnulib module: --- Portability problems fixed by Gnulib: @itemize @end itemize Portability problems not fixed by Gnulib: @itemize @item 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. @end itemize
