comparison rogue3/mdport.c @ 252:3d4252fa2ed3

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use more portable random seed generation. The new function md_random_seed() has replaced time() + getpid() and similar methods. Putting everything in mdport.c slightly reduces the warnings and workarounds.
