Howdy,

Heikki asked me to look at the renames of the static Meson targets.=20
I don't understand the reasoning for the changes. I am completely=20
unfamiliar with AIX, so maybe it's obvious. Does Meson produce a static=20
library and a shared library with the same file extension? If so, why is=20
that? That's the only reason I can think of for making those changes. Is=20
it AIX-specific or whatever OS you are testing on?

In your patch, I found a link to=20

This seems to imply that we don't need a static library at all on AIX.=20
However this email is also nearing 20 years old :D. Could we get away=20
without the renames on the Meson targets by just not defining the static=20
library targets?
