Dear Professor Ripley,

as you pointed out, package 'memisc' caused a compilation error with the Sun Studio compiler because of gcc-specific compilation flags. The obvious reason was that the 'src' directory had a 'Makevars' file containing "PKGC_FLAGS="-Wall -pedantic".

In the new revision of my package uploaded this weekend, the Makevars file is removed, but nevertheless according to the protocol of the automatic package checking with Sun Studio (of 2009-02-10 05:53:33), a compilation error occurs because of the gcc-specific compilation options "-Wall -pedantic". I checked the CRAN-version of the package for any instances of Makefiles or Makevar files, but none is present. Also I grepped my sources for any instance of "-Wall", with negative results. So I wonder what I should do to avoid Sun Studio errors caused by these options.

Any hint is appreciated.
Thanks,

Martin Elff
