Building GHC 6.12 with GHC 6.12 + alex

[Antoine Latter]

Folks,

I've run into trouble building GHC 6.12 with alex built from GHC 6.12:

"/Users/alatter/usr/bin/alex"  -g compiler/parser/Lexer.x -o
compiler/stage1/build/Lexer.hs
alex: compiler/parser/Lexer.x: hGetContents: invalid argument (Illegal
byte sequence)

however things like:

ghci> readFile "compiler/parser/Lexer.x"

apear to work just fine. Has anyone else seen this? Has anyone else
succeeded in this?

This is on Mac OS X 10.6, running on Intel Core 2 Duo. I'm trying to
compile a recent pull of the 6.12 branch.

Thanks,
Antoine
