External Core front end is completely broken

[Kirsten Chevalier]

Using the latest version of GHC downloaded from CVS, it's impossible to use
GHC to compile any .hcr files that it generates itself. The reason for this
is that, as per the CVS log for prelude/PrelNames.lhs, all "Main" modules now
contain a definition for $Main.main -- however, the External Core lexer
still requires module names to begin with an upper-case letter, resulting in
a parse error.
