Thank you jwe.
According to your advice I searched config.log.

configure:17892: checking for sigset_t
configure:17931: gcc -c -O2 -I/mingw/include -I/usr/local/octave-2.9.13/include 
-I/GnuWin32/include
conftest.c >&5
conftest.c:63: error: syntax error before "ac__type_new_"
conftest.c:63: warning: data definition has no type or storage class
conftest.c: In function `main':
conftest.c:75: error: syntax error before ')' token
configure:17937: $? = 1

Then I erased '//'
#if !defined(HAVE_SIGSET_T)
typedef int sigset_t;
#endif

then did 'make clean'; 'make'
***********
making i1mach.def from i1mach.f
touch stmp-pic

Then again '//' was added 
#if !defined(HAVE_SIGSET_T)
//typedef int sigset_t;
#endif
'make' was secceded to compile  machar.c.

 
Summary 
1. The 'typedef sigset_t' exists in tbe ...include/sys/types.h
2. In .confubure, it failed
 The conftest.c test failed in ./configure process,
 conftest.c:63: error: syntax error before "ac__type_new_"
3.However, 'typedef sigset_t' in ...include/sys/types.h
4.In confifure.in 
  AC_CHECK_TYPES([sigset_t, sig_atomic_t], , , [#include <signal.h>])
5. In ...include/sys of mingw gcc, there is no 'sigset_t' in 
...include/signal.h but in
...include/sys/types.h

That was reason that 'typedef int sigset_t' was set config.h for mingw.


I cannot remember Benjamin  used glibc instead of the default includes.
(I re-searced ML, I cannot found the glibc description.)
However he did not mentioned this, it is possible for him to use glibc.
