Thanks for the report. Hmm... are you using the released tarball or
the version from the darcs repository?
which files did you need to change to get it to compile against 7.04?
I am still mainly on 6.12 but would like to have it compatible with
both.

Hi all,
The generated C source hs.out_code.c cannot be compiled due to an undeclared variable. Here is the snippet code which can reproduce the issue.
import Data.Array.IO main = do arr <- newIOArray (0,42) 0 :: IO (IOArray Int Int) print 13
Here is the excerpt from jhc's output:
Writing "hs.out_code.c" Running: gcc '-std=gnu99' -D_GNU_SOURCE '-falign-functions=4' -ffast-math -Wextra -Wall -Wno-unused-parameter -fno-strict-aliasing -o hs.out hs.out_code.c -DNDEBUG -O3 '-D_JHC_GC=_JHC_GC_JGC' hs.out_code.c: In function ‘ftheMain’: hs.out_code.c:1867:27: error: ‘v119549094’ undeclared (first use in this function) hs.out_code.c:1867:27: note: each undeclared identifier is reported only once for each function it appears in hs.out_code.c: In function ‘fx57580221’: hs.out_code.c:1886:24: warning: comparison between signed and unsigned integer expressions hs.out_code.c:1889:9: warning: statement with no effect hs.out_code.c:1926:17: warning: statement with no effect jhc: user error (C code did not compile.)
The whole session is enclosed as `typescript'.
Btw, jhc 7.7 cannnot be compiled on ghc 7.0.4 smoothly. I add `{-# LANGUAGE TypeFamilies #-}' and `import Data.Generics hiding (empty)' to get it compiled.
