make_gdl -d option isn't accepted

[bobh0303]

The -d short-name option gives an error:

me@mine:~$ make_gdl -d LateefReg.ttf x.gdl
Option d, key "LateefReg.ttf", requires a value

The problem has been around since 2012 when -D was added and we changed to use long options. We have the following option specifications:

'autodefines|d',
'define|D=s%', 

but, in the default configuration GetOptions() is case-insensitive. Note that --autodefines works, but -d is treated by GetOptions as --define which requires a key=value parameter.

Some possible approaches:

• Enable GetOptions case sensitivity by setting no_ignore_case -- affects all options (single letter and long) so will require lowercase options everywhere except for -D
• Turn on first level of GetOption "bundling" (by setting bundling) which allows single-letter options to be bundled together. According to the manpage, "When configured for bundling, single-character options are matched case sensitive while long options are matched case insensitive."
• Remove the -d option, requiring the longer --autodefines.

Either of the first two approaches will break a build that uses uppercase option letters (other than -D) and thus is depending on the case-insensitive nature of the current option parsing.

Neither make_volt nor make_fea currently implement either of these options.

Suggestions welcome.

We've concluded that, since -d is currently broken and many of our projects use --autodefines instead, the safest fix is to take the 3rd option above (remove -d and require the longer --autodefines).
