Argh... MBCS. I tried running wine with debug on,
( WINEDEBUG=+relay wine Rgui.exe 2>&1 ) and it shows that just before 
2.4.1/2.5dev crashes, R tried to called strlen() and strchr() on
"Error: invalid multibyte string" in ntdll.

Call ntdll.strlen(6c9a0a80 "Error: invalid multibyte string\n") ret=6c9150bd
Call ntdll.strchr(00e192e0 "Error: invalid multibyte string\n",0000000a) 
ret=6c704ec0

It might be bogus, but the same trace is not found in
WINEDEBUG=+relay wine Rgui.exe 2>&1
with R 2.4.0 .

Can I have a svn revision number for the MBCS change please? It
should probably be the first thing I look at, as soon as I get
my cross-compile tools up to date... thanks a lot.
