TL;DR
gcc-8.3.0 is now available on gcc302 as:

    /usr/local/bin/x86_64-unknown-openbsd6.5-gcc-8.3.0

or simply as:

    egcc

Notice above that this old version of gcc-4.2.1 *was* upgraded to kernel
6.5 (see the "Target:" and the "Reading specs from").

I'm no OpenBSD expert, but I believe that gcc-4.2.1 is the last gcc
version which is bundled as 'native' package in core OpenBSD sets -
because it was the last version released under GPLv2 (not sure about the
terminology of packages/sets here, but I hope you get the gist).

Other versions (e.g. gcc-8.3.0 and many other GPLv3 packages) are
of course available but need to be installed explicitly.

That is, "gcc-4.2.1" will never be upgraded to newer gcc version with
a simple "pkg_add -u" (which is the command to upgrade the user-space
packages).

You can see that the OpenBSD man-page for "gcc" is for version 4.2.1,
and "gcc-local" gives further modifications for OpenBSD:
https://man.openbsd.org/OpenBSD-current/gcc
http://man.openbsd.org/OpenBSD-current/man1/gcc-local.1

In the release notes page ( https://www.openbsd.org/65.html ),
you'll see that "gcc-8.3.0" and "gcc-4.9.4" are listed under "ports and 
packages",  while "gcc-4.2.1" is still listed under "The system includes 
the following major components from outside suppliers".

Anyway,

I've installed "gcc-8.3.0" in the paths listed above,
So building with
    ./configure CC=egcc
    make CC=egcc
or something similar "should work".


Hope this helps,
And let me know if other packages are needed.
