The underlying lapack32.lib plus lapack32.dll plud blas32.lib plus
blas32.dll *could* be compiled by everyone, "simply" by retrieving the
original LAPACK.tgz source package plus applying the contrib/lapack.diff
patch included in our lapackpp source package. *However* I understand
not everyone is familiar in doing so. Also, these libraries haven't
changed at all during the last 2-3 years. So I ship these four files in
compiled form in the lapackpp-setup.exe packages, but they are really
identical from version to version.

So to answer your question: The lapack32.lib etc. files in the older
setup.exe packages are still up to date. Please simply use them from the
older setup.exe packages -- but make sure you *don't* use the lapackpp
header files from the older setup.exe packages.

Yes they are.

What do you mean by "complex inverse matrix"? There are matrices of
complex numbers in include/gmc.h, although they will only be compiled
when LA_COMPLEX_SUPPORT is defined, which by default is not the case for
MSVC. Is this what you are looking for?
