Thanks for the patch, and sorry for taking so long to get to it. I've pushed it

    gst-parser.m4: Fix Bison version check to handle development versions of
GNU Bison

    Fixes
    checking bison version 2.7.1.1194-51a4 >= 2.4... Bareword found where
operator
    expected at -e line 1, near "51a4"
        (Missing operator before a4?)
    syntax error at -e line 1, near "51a4 "
    Execution of -e aborted due to compilation errors.

    This is due to not quoting the string when calling 'perl' to check
    the version number. The - sign causes a syntax error.
