Re: add cegcc support

[Ralf Wildenhues]

Hello,

after some more hashing off-list (and lots of delays on my side, sorry
about that), I've applied this patch now.

Please post verbose output for any remaining test failures.

Thanks again,
Ralf

2008-08-01  Vincent Torri  <address@hidden>

        Add cegcc (Windows CE/PocketPC) support.
        * libltdl/config/ltmain.m4sh: Add 'cegcc' case where needed.
        * libltdl/m4/libtool.m4 (LT_CMD_MAX_LEN, LT_SYS_DLOPEN_SELF)
        (_LT_SYS_DYNAMIC_LINKER, _LT_CHECK_MAGIC_METHOD)
        (_LT_CMD_GLOBAL_SYMBOLS, _LT_COMPILER_PIC, _LT_LINKER_SHLIBS)
        (_LT_LANG_CXX_CONFIG): Likewise.
        * libltdl/m4/ltoptions.m4 (AC_LIBTOOL_DLOPEN): Likewise.
        * NEWS: Update.
        * THANKS: Update.
