MSYS+MSVC for libtool head, take 9

[Peter Ekberg]

Hi!

This one depends on the 'head-lib-as-archiver' patch. But this
patch is diffed against a clean tree, so it might be some fuzz
applying it after applying lib-as-archiver.

I have left out the fixes for the test suite, so some
tests fail due to the testsuite not being in shape for
MSVC. I have fixes for all but two failures in the old
testsuite, for those who have not been following closely.

        * config/ltmain.m4sh (func_dashL_to_envvar): New function,
        moves -L linker options to the dashL_envvar environment
        variable.
        * config/ltmain.m4sh (func_mode_compile) [MSVC]: For C++, add
        the option -TP to the compiler and for C, add the option -TC.
        * config/ltmain.m4sh (func_mode_link) [MSVC]: There is no math
        library, so drop -lm. The -lfoo notation is not supported, so
        convert such occurances to foo.lib. Treat library file names
        without regard for case, through the use of file_magic_glob.
        When command line length is exceeded during generation of
        exported symbols, build a temporary archive using a command
        file and export the symbols from that archive. When command
        line length is exceeded during archive linking, use a command
        file.
        * config/ltmain.m4sh (func_mode_link): If the -L flag is not
        supported, but additional library paths can be specified with
        an environment variable, do so using the new function
        func_dashL_to_envvar.
        * config/ltmain.m4sh (cwrappersource) [MSVC]: Make it compile.
        * config/ltmain.m4sh (funk_mode_link) <prog>: Build the
        cwrapper first and then strip the results.
        * m4/libtool.m4 (_LT_SYS_DYNAMIC_LINKER) [MSVC]: Flesh out
        with a lot of missing bits.
        * m4/libtool.m4 (_LT_CHECK_MAGIC_METHOD): New _LT_DECL variable
        file_magic_glob, which can be used to have some fuzzyness when
        searching for a matching library.
        * m4/libtool.m4 (_LT_LINKER_SHLIBS): New _LT_DECL variables
        dashL_envvar and dashL_envvar_spec.
        * m4/libtool.m4 (_LT_LINKER_SHLIBS) [MSVC]: Make use of
        dashL_envvar and flesh out a lot of other missing bits.
        * m4/libtool.m4 (_LT_LANG_CXX_CONFIG) [MSVC]: Add support for
        MSVC++ as a C++ compiler.
        * NEWS: Updated.

Cheers,
Peter
