[icecast-dev] [PATCH] main.c: use pid_t and cleanup command line opts parsing.

[Dale Ghent]

Use pid_t instead of int for variable processID

Add error message if fork() fails.

Do not immediately return() after encountering the -c flag - we may still
have additional argv members to find and take care of.
