Log-message for: Improve command-line parser (add OptIntSuffix); make -fliberate-case-threshold dynamic (Alas, Darcs failed to record my log-message for the above patch, so this patch is an attempt to add the log message retrospectively.) Parsing options numeric arguments, such as -fliberate-case-threshold=30 for dynamic flags wasn't being handled well. I elaborated the command-line parser to have a new constructor, OptIntSuffix, for this case, and did the consequential changes. This patch also makes the -fliberate-case-threshold flag into a dynamic flag.
