The way Ada handles this is by lower-casing the expression being used
as the key, and then comparing it with the name stored in our symbol.
For instance, if the user does:

        (gdb) print My_Variable

What GDB does is first lower-case "My_Variable" to "my_variable", and
then do a search of my_variable.

You could transpose that to Pascal by upper-casing My_Variable the
entity name in the expression before doing the search.

Using Ada as an example, we have the same sort of issue, and what
we have been using is a special syntax to tell the parser to avoid
the casing-change:

        (gdb) print <My_Variable>

Maybe you can do something similar for Pascal?
