    “auto” implies that a value is being chosen based on build system introspection or host system capabilities. However, for the --with-ecmult-window and --with-ecmult-gen-kb options, the values “auto” are hardcoded, which might lead to confusion.

    This PR replaces “auto” with more appropriate default values.

    If Concept ACKed, I’ll add equivalent commits for CMake.

    Concept ACK from my side

    I think having a default is good enough, we don’t need two layers of indirection (default -> auto -> some number).

    utACK 4d9645bee06e732f5d7d9e72b0c26c22c5006eb8 good from my side, but let’s see if we can get more (Concept) ACKs

    I think we’d still want to have something like profiles (e.g., “desktop”, “embedded”, “minimal”) eventually, but this change makes sense independently of this.

    Does this need a changelog entry? Strictly speaking yes because this removes a valid config option. But pragmatically, I tend to say no: the breakage occurs only for people who passed =auto (the default) explicitly, so this should hardly affect anyone.

    edit: Let me just add the label, we can revisit this when we do the release.
