patch applied (cabal): Warn if C dependencies not found (kind of fixes #262)

Mon Jan 26 10:58:32 PST 2009 gleb.alexeev@gmail.com * Warn if C dependencies not found (kind of fixes #262) This is just a basic check - generate a sample program and check if it compiles and links with relevant flags. Error messages (warning messages, actually) could use some improvement.
