complie error of cquit.c (libcruft) (MinGW build for 3.5.50+)

[Tatsuro MATSUOKA]

Hello 

Perhaps the error comes from the gnulib renewal.

        * acinclude.m4 (OCTAVE_CXX_COMPLEX_REFERENCE_ACCESSORS,
        OCTAVE_CXX_COMPLEX_SETTERS): New macros.
        * configure.ac: Use them.

***********************

signal.h of mingw lacks SIG_SETMASK 

#define SIGINT          2       /* Interactive attention */
#define SIGILL          4       /* Illegal instruction */
#define SIGFPE          8       /* Floating point error */
#define SIGSEGV         11      /* Segmentation violation */
#define SIGTERM         15      /* Termination request */
#define SIGBREAK        21      /* Control-break */
#define SIGABRT         22      /* Abnormal termination (abort) */

However importing gnulib signal.h does not recover the portability for 
SIG_SETMASK.
The signal.h produced by gnulib for my system is attached.


In the manual of gnulib
http://www.gnu.org/software/gnulib/manual/gnulib.html#signal_002eh

5.42 signal.h

Portability problems not fixed by Gnulib: 
Many signals are not defined on some platforms: mingw.

Unfortunately the lack of SIG_SETMASK may not be resolved by importing gnulib 
on mingw.
