patch applied (cabal): Arch and OS names were previously allowed to contain "_-", restore that.

Wed Mar 26 17:46:31 PDT 2008 Duncan Coutts * Arch and OS names were previously allowed to contain "_-", restore that. That is the arch and os strings in conditionals in .cabal files, like: if arch(x86_64) Previously the parser used isAlphaNum c || (c `elem` "_-"). This is crucial for arch names like "x86_64". So make the new parser for OS and Arch types use the same string parser as before (there is a string parse part and a separate classification of known OS/Arch values).
