Subject: [Rd] Problem with WARNING...headers with CRLF line endings

Dear all,

When running R CMD check on Windows XP to test my package I get the
following warning message:

"* checking line endings in C/C++/Fortran sources/headers ... WARNING
Found the following sources/headers with CR or CRLF line endings:
    src/xpsDict.h"

The problem is that this file is created by the compiler
AUTOMATICALLY
during the compilation process, and since the file is created
by VC++ on
WinXP, it will always have CRLF line endings.

Thus my question is:
- Is it really necessary to issues this warning message?
- If yes, could it be suppressed on Windows XP, since there it should
obviously be no problem.

Older versions of Sun C compilers would refuse to
compile code with Windows-style line endings.  I don't
know if that is still the case.  One reason to run check
is to see if there are any platform-dependencies in
code on CRAN so the warning should not be suppressed.

(The S+ package system tries to avoid the problem by changing
line endings on text files when it compiles the package.
It is not trivial to reliably figure out which files are
meant to be text files.)

One more issue:
While I have always received this warning on my WinXP
installation, for
some lucky reason the warning did until now not appear on the
Bioconductor Windows server, see BioC 2.6 with R-2.11.1:
http://bioconductor.org/checkResults/2.6/bioc-LATEST/xps/liver

pool-checksrc.html

However, for some reason on BioC 2.7 running R-2.12.0 this
warning does
appear, see:
http://bioconductor.org/checkResults/2.7/bioc-LATEST/xps/liver

pool-checksrc.html

For this reason I would  appreciate if there would be a
possibility to
suppress this warning message.

Thank you in advance.
Best regards
Christian
