Other misc cygwin fixes

[Charles Wilson]

While poring over the libtool code, I found a few nits with cygwin/mingw 
support.  This patch addresses those.

2002-11-01  Charles Wilson  <address@hidden>

        * libtool.m4 ([AC_LIBTOOL_DLOPEN_SELF): cygwin uses 'dlopen'
        not LoadLibrary.
        (AC_LIBTOOL_PROG_LD_SHLIBS): no need to special case
        cygwin/mingw/pw based on dlltool limitations; we now use ld
        like other GNU targets.
