curious package behaviors under cross-build and/or between windows/unix

Hi, I have gone back to cross-compiling again, and I have come to two curious issues: (I have native R under linux x86_64 and win32 R under wine) - both 2.4.1: (1) for a pure R package (i.e. no compiled code), win32 R would happily load the unix version, but the unix version complains the cross-built package that it was built for x86 mingw and refuses to load it. Is there any reason for the difference?
Yes. Take a look at the installed DESCRIPTION file, and the Built: line. (One reason is line endings: not everything works on Unix (diff, for one) with CRLF endings, but everything does work on Windows with LF endings.)
(2) I get two "arguments in definition changed from (obj) to (object)" messages when I do library(XML) on win32 R - but not on native R,
I get it on all platforms with 2.5.0 RC and later (2.4.x is closed), and it is a bug in the XML package, AFAICS.
I know R-devel is not for asking omegahat questions, but the message seem to be emitted by R core, so for some reason win32 R is behaving differently from native linux R. Again, why the difference in behavior? Thanks for an ideas. Hin-Tak Leung
