Samba configure problem on Solaris 10 with Studio 11

[David Collier-Brown]

   I had to buy a new disk for froggy, so I took the opportunity to
upgrade to Solaris 10 and the Sun Studio 11 compilers.
   I now find a false [positive from configure, on both samba 3 and 4

configure reports
---
froggy> ./configure 2>&1 | tee oops.log

Aborting config

This is in testing the code
---
+ eval echo 'configure:27882: "$CC -o conftest$ac_exeext $CFLAGS 
$CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS >&5"'
--
where the conftest file contains
---
cat confdefs.h >>conftest.$ac_ext
cat >>conftest.$ac_ext <<_ACEOF
/* end confdefs.h.  */

/* Override any gcc2 internal prototype to avoid an error.  */
#ifdef __cplusplus
extern "C"
#endif
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char pam_start ();
int
main ()
{
pam_start ();
   ;
   return 0;
}
_ACEOF
---

   I can happily compile and link this test against -lpam
on my system, but configure can't:
froggy> cc -o conftest conftest.c -lpam
froggy>

   I have sh -x output, but running it with -x
causes it to pass the tests (;-))
   I'll put the rest of the material into a bug
report, #3360.
