$NetBSD: patch-configure,v 1.3 2022/06/19 14:43:28 gdt Exp $

Add support for MirBSD as OpenBSD and DragonFly as FreeBSD.

Upstream has support to use the version with or without dots as the
shlib suffix, conditioned on TCL_LIB_VERSIONS_OK.  This patch forces
that to be the "NODOTS" flavor always.  \todo Explain the plan; this
seems likely to make the build the same on all pkgsrc platforms.

Define PVNODOTS and use it to overwrite SHARED_LIB_SUFFIX and
define UNSHARED_LIB_SUFFIX.  PVNODOTS appears to have the same value as
PACKAGE_VERSION_NO_DOTS, that upstream configure already computes.
\todo Explain why there is a new variable.

Add support for SVR5 and OpenServer 5.  Sent upstream by email
September 2019.

Substitute the already-computed SHLIB_VERSION, for use in Makefile.in.

\todo File changes upstream (but upstream is not functioning).
