Compiling a testdir for 'spawn' on mingw, I see this error:
../gllib/spawn.h:406: error: `POSIX_SPAWN_RESETIDS' undeclared here (not in a
function)
../gllib/spawn.h:407: error: `POSIX_SPAWN_SETPGROUP' undeclared here (not in a
function)
../gllib/spawn.h:407: error: `POSIX_SPAWN_SETSIGDEF' undeclared here (not in a
function)
../gllib/spawn.h:408: error: `POSIX_SPAWN_SETSIGMASK' undeclared here (not in a
function)
This fixes it.

Fix compilation error when modules 'posix_spawn[p]' are not used.
* m4/spawn_h.m4 (gl_SPAWN_H): Set HAVE_POSIX_SPAWN here.
* m4/posix_spawn.m4 (gl_POSIX_SPAWN_BODY): ... not here.
