Revert "Cygwin: glob: perform ignore_case_with_glob on input"
This reverts commit a51147467e6cf58618433286f93d17043e00b0fc. Dumb thinko on my part. What was supposed to be an optimization actually broke caseinsensitive globbing in that the entire input of globbed expressions were downcased. Drop the unused CCHAR() macro nevertheless.
