Subject: [PATCH v2 2/6] mingw: drop the build-system plumbing for nedmalloc

From: "Johannes Schindelin via GitGitGadget" <[email-masked]>
Date: Thu, 07 May 2026 16:00:09 +0000

From: Johannes Schindelin <[email-masked]>

With the previous commit removing every opt-in, the build-system
plumbing for nedmalloc has nothing left to switch on. Remove it so
that the upcoming deletion of the compat/nedmalloc/ tree is a pure
file removal.
