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

[Tatsuro MATSUOKA]

Hello

Sorry I have found in signal.h
line 355-361
# if !0
#  define SIG_BLOCK   0  /* blocked_set = blocked_set | *set; */
#  define SIG_SETMASK 1  /* blocked_set = *set; */
#  define SIG_UNBLOCK 2  /* blocked_set = blocked_set & ~*set; */
_GL_FUNCDECL_SYS (sigprocmask, int,
                  (int operation, const sigset_t *set, sigset_t *old_set));
# endif

gcc -shared-libgcc -DHAVE_CONFIG_H -I. -I../../../hg/octave-work/libcruft
 -I..
 -I/WinDevTools/include -I/GnuWin32/include -O3 -fomit-frame-pointer

 misc/libcruft_la-cquit.lo -MD
 -MP -MF misc/.deps/libcruft_la-cquit.Tpo -c 
../../../hg/octave-work/libcruft/misc/cquit.c  

Hmmmm, it seems that -I../libgnu missing in the complier flag.
