stdlib self test: error: 'SIGTERM' undeclared

[Simon Josefsson]

This command:

gnulib-tool --create-testdir --dir m --with-tests stdlib; cd m ; ./configure 
--host=i586-mingw32msvc --build=i686-pc-linux-gnu ; make

results in:

test-stdlib.c: In function ‘main’:
test-stdlib.c:63: error: ‘SIGTERM’ undeclared (first use in this function)
test-stdlib.c:63: error: (Each undeclared identifier is reported only once
test-stdlib.c:63: error: for each function it appears in.)

the cause is gnulib's stdlib.h:

#ifndef WEXITSTATUS
# include <sys/wait.h>
#endif

and in turn gnulib's sys/wait.h:

# define WTERMSIG(x) SIGTERM

But sys/wait.h never includes <signal.h> to get SIGTERM.

Bruno, is the patch against the sys_wait module below OK?
