PATCH: CommonC++-1.50/m4 vs. autoconf-2.50

[Adam J. Richter]

        Under autoconf-2.50, the AC_CHECK_LIB(mylib,mysymbol) macro
builds shell variables with names like "$ac_cv_mylib_mysymbol".  If a
couple of files in the CommonC++-2.50/m4/ directory, you use a shell
variable for "mylib", like so:

         AC_CHECK_LIB($ost_cv_thread_library, nanosleep,
                ...

        The problem is that the resulting ./configure file checks
the variable $ost_cv_thread_library_nanosleep" instead of
${$ost_cv_thread_library)_nanosleep.  The following patch
seems to work around the problem.

        I think ths may arguably be an autoconf-2.50 bug, so
I am cc'ing this to address@hidden for their information.

        Even if this is an autoconf bug, I believe that applying the
following patch to CommonC++ should be harmless, so I recommend that
you do it anyhow, to work with the existing autoconf-2.50 release in
any case.
