Quoting http://bugs.debian.org/457933 :

I have the following enum definition in a file called beef_instruction.h,
and I want it to be converted into a GEnum derived type.

    typedef enum {
        BEEF_INSTRUCTION_NONE        = '\0',
        BEEF_INSTRUCTION_PREVIOUS    = '<',
        BEEF_INSTRUCTION_NEXT        = '>',
        BEEF_INSTRUCTION_INCREASE    = '+',
        BEEF_INSTRUCTION_DECREASE    = '-',
        BEEF_INSTRUCTION_LOOP_BEGIN  = '[',
        BEEF_INSTRUCTION_LOOP_END    = ']',
        BEEF_INSTRUCTION_READ        = ',',
        BEEF_INSTRUCTION_PRINT       = '.',
        BEEF_INSTRUCTION_TAPE_DUMP   = '#'
    } BeefInstructionValue;

I think the code is legit and glib-mkenums should be able to handle it, but
the value of BEEF_INSTRUCTION_READ is skipped in the output files, and the
following error message is displayed:

    /usr/bin/glib-mkenums: beef_instruction.h:23: Failed to parse `
BEEF_INSTRUCTION_READ        = ',', '

Please consider fixing this, or let me know if the problem lies in my code.
