Dear Uwe,
first test versions are always by definition incorrectly
working versions.
Reading
http://cran.r-project.org/doc/manuals/R-admin.html#BLAS
http://cran.r-project.org/doc/manuals/R-admin.html#LAPACK
it is clear that R relies with its internal BLAS and Lapack
implementation, differently from a lot of other packages.
May I suggest to add an additional note that also
external BLAS is not recommended as done for LAPACK.
It will be also worth to add a "not recommended" on the
configure --help
output
--with-blas use system BLAS library (if available),
or specify it [no]
--with-lapack use system LAPACK library (if available),
or specify it [no]
as it is not obvious and it could mislead newcomers like me.
External BLASs work for me perfectly on other platforms than cygwin.
Hence it is cygwin that I would not recommend given the native Windows
version is both faster and passes the checks.
