I've encountered problems building this newer PKGREVISION of mail/nmh on
my netbsd-1-6 alpha.

    $ uname -smr 
    NetBSD 1.6.2_STABLE alpha

The previous revision (nmh-1.0.4nb5) worked just fine, but this one
blows up real good in the compile.

It appears as though POSIX_SIGNALS should be defined, but isn't.  This
seems to be due to the configure checks for the likes of sigaction,
sigprocmask, sighold, sigrelse, et al are not including <signal.h>.

; return 0; }

Does anyone have any hints/suggestions (besides maybe netbsd-specific
patching of configure or tricking it with the appropriate environment
settings)?  I wonder if moving the signal.h check up to before the
sig*() checks would suffice.
