AC_CHECK_LIB small problem which Solaris C compiler |

Hi,
I just tested CVS autoconf under Solaris 2.5.1 and found a small
problem with AC_CHECK_LIB macro.
Under some circumstances, some temporary files remains, which generate
testsuite failures (by example with `AC_IRIX_SUN' macro, see
testsuite.log below).
This problem appears if AC_CHECK_LIB result is `no'.
AC_CHECK_LIB(m, log) ... works fine
AC_CHECK_LIB(m, log200) ... problem
I tracked down the problem and found that Solaris cc compiler do not
remove temporary compilations files if link pass fails.
One solution can be to force cleaning of `conftest.$ac_objext' in
`_AC_LINK_IFELSE' macro.
NB: configure script remove this files at the end using the trap.
