build fails on Linux/sparc (genprimopcode: parse error at)

Description (Last modified by simonmar) 

Build fails when building ghc 6.4.x (tested 6.4 and 6.4.1) on Linux/
sparc and using ghc 6.4 binaries for bootstrap:

mkdir stage1/ndpFlatten
mkdir stage1/iface
mkdir stage1/cmm
mkdir stage1/ghci
Creating main/Config.hs ...
done.

Done.

The same problem doesn't exists when using ghc 6.2.x for 
bootstrapping (generated primops.txt is the same in both cases, 
tested via md5sum). Problem doesn't exists on other arch like x86, 
ppc, amd64,  too.

perhaps there's something odd about your gcc.  Can you
upload a copy of primiops.txt?  (it'll be in
ghc/compiler/prelude).

isSpace doesn't work correctly

[builder@fiskus ~]$ cat Test.hs
import Char
main = print (isSpace '\t')
[builder@fiskus ~]$ ghc Test.hs -o Test && ./Test
False
[builder@fiskus ~]$ ghc --version

more complete test:
[builder@fiskus ~]$ ghc Test.hs -o Test && ./Test
[True,False,True,True,False,True]
[builder@fiskus ~]$ cat Test.hs
import Char; main = print (map isSpace " \t\n\r\f\v")

Not a GHC bug (probably). It was later discovered that gcc 4.0 works correctly for this example, but 3.3.6 fails.
