I agree. It is more flexible.
How about the following?

(defcustom gtags-ignore-case 'follow-case-fold-search
  "*Controls whether or not ignore case in each search."
  :type '(choice (const :tag "Follows 'case-fold-search variable" 
follow-case-fold-search)
                 (const :tag "Ignore case" t)
                 (const :tag "Distinguish case" nil))
  :group 'gtags)


[Usage of gtags-ignore-case]

(setq gtags-ignore-case t)                              ; ignore case

(setq gtags-ignore-case nil)                            ; distinguish case

(setq gtags-ignore-case 'follow-case-fold-search)       ; follow 
'case-fold-search variable

The default is 'follow-case-fold-search.

What do you think?
