[ECOS] Bug in Config tool 2.04 with invalid CDL options

["Trenton D. Adams" <trent dot nospam at telusplanet dot net>]

Take for instance the "<cyg/error/codes.h>" below.  If it's not 0, the
config tool 2.04 will lock up indefinately.  Although there shouldn't be
errors in the CDL files, the program shouldn't lock up either.  I don't
know if this is worth fixing or not.

Where's the source code for the GUI config tool anyhow?  Maybe if I get
enough time I can fix these little problems.  After all, I'm a better
windows developer than I am eCos! Lol.

    cdl_component CYGPKG_ISO_ERRNO {
        display       "Error handling"
        flavor        none
        no_define

        cdl_interface CYGINT_ISO_ERRNO_CODES {
            display       "Number of implementations of error codes"
            requires      { 1 >= CYGINT_ISO_ERRNO_CODES }
        }
    
        cdl_option CYGBLD_ISO_ERRNO_CODES_HEADER {
            display       "Error codes implementation header"
            flavor        booldata
            default_value 0
        }
    
        cdl_interface CYGINT_ISO_ERRNO {
            display       "Number of implementations of errno variable"
            requires      { 1 >= CYGINT_ISO_ERRNO }
        }
    
        cdl_option CYGBLD_ISO_ERRNO_HEADER {
            display       "errno variable implementation header"
            flavor        booldata
            default_value 0
        }
    
    }
