You are asking these questions in the wrong forum.  The package you
downloaded was clearly built using a port of GCC that is not the one
distributed by mingw.org.  E.g., the GCC distributed by mingw.org was
never configured to use SEH exceptions, AFAIK, so it cannot have
libgcc_s_seh-1.dll.

So the best way to solve your problem is to ask the person(s) who
produced the netlib-java package to tell you where to find the exact
version of GCC they used to build that package.  Trying to use any
other similarly-called DLLs will only get you in trouble, because of
incompatibilities between different ports of GCC.

As a side note, I think people who provide precompiled binaries that
depend on DLLs specific to certain GCC ports are making a disservice
to their users.  They should at the very least provide those DLLs from
the same site as the binaries they distribute, or even in the same
archive.  But that's me.
