"pexports" is its own package in OpenSUSE, although it looks like
"gendef" (or even libtool itself) might be the preferred way to generate
.def files nowadays.

"make-lib.sh" is in the "bin" directory in
gnutls-2.12.18-1.2-win32ws.zip. It's just a series of "lib" commands, e.g.

lib /machine:x86 /def:libgcrypt-11.def /name:libgcrypt-11.dll \
  /out:libgcrypt-11.lib

It looks like that's an exception handling library which can be linked
statically:

GnuTLS switched to LGPLv3+ in version 3.0, then back to LGPLv2.1+ in
version 3.1.10. We need switch to a newer 3.x release at some point
since the 2.12 branch is no longer maintained as far as I know. However,
we need to be careful with the version of GMP that we ship since it
switched to LGPLv3+:
