1.2.2 on HP-UX

[Anthony Kim]

gnupg-1.2.2 fails to build on HP-UX at cipher/random.c:

random.c: In function `fast_random_poll':
random.c:655: storage size of `buf' isn't known
random.c:656: warning: implicit declaration of function `times'
random.c:655: warning: unused variable `buf'

As it turns out, we are not including <sys/times.h> because
the configure test for gettimeofday failed:

configure:12938: checking for gettimeofday
configure:12988: gcc -o conftest -g -O2   conftest.c  >&5
configure:13055: conflicting types for `gettimeofday'
/usr/include/sys/time.h:485: previous declaration of `gettimeofday'

I ran the test program copied from config.log.  Apparently HP
does not like <limits.h>

[snip]
#ifdef __STDC__
# include <limits.h>
#else
# include <assert.h>
#endif

So when I use <assert.h> the test builds fine.

[Previously, 1.2.1 configure used <assert.h> so I never came across this
before.]

I can do CPPFLAGS=-DGETTIMEOFDAY <- bleh!
or patch configure to remove limits.h but I wonder if there is a
"correct" way of handling this.
