Useless hours spend on tracking cvs bug with libc. I wanted to compile cvs but then broken getopt caused wrong command line options parsing, and afterwards my cvs didn't understand any commands at all. Workaround was rather simple, force cvs to use its own (GNU) implementation of getopt (well, no configure magic here, just some __GNU__LIBRARY!). Also, a bit tweaking is required to fix some other odd behaviours.
