Python (i.e., Distutils) is checking versions so that it calls the
appropriate driver and supplies the appropriate options.  For example,
in cygwinccompiler.py we have the following:

    # ld_version >= "2.10.90" and < "2.13" should also be able to use
    # gcc -mdll instead of dllwrap
    # Older dllwraps had own version numbers, newer ones use the
    # same as the rest of binutils ( also ld )
    # dllwrap 2.10.90 is buggy
    if self.ld_version >= "2.10.90":
        self.linker_dll = "gcc"
    else:
        self.linker_dll = "dllwrap"
            
    # ld_version >= "2.13" support -shared so use it instead of
    # -mdll -static
    if self.ld_version >= "2.13":
        shared_option = "-shared"
    else:
        shared_option = "-mdll -static"

Agreed, but this stuff predates me (i.e., before 2000), so I loathe to
touch it... :,)
