Bug ID: 57106
           Summary: configure: prevent using --enable-win64 and
                    --enable-archs=x86_64,i386 together
           Product: Wine
           Version: 9.16
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Keywords: download, source, wow64
          Severity: normal
          Priority: P2
         Component: build-env
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: Debian

I noticed this in bug 57084 (the same user has reported doing the same in bug
57103 and bug 57104).

Testing locally, if both are passed, regardless of order, then
--enable-archs=x86_64,i386 is what takes effect.

However since these aren't meant to be used together, configure should probably
warn/error out if both are passed.
