diff configure.ac @ 30510:e0e22183ffca stable
Restore building with visibility flags for Windows.
* configure.ac: Windows uses a dllexport/dllimport mechanism instead of
visibility attributes. Don't deactivate visibility flags on that platform if
HAVE_VISIBILITY is 0 (which it will always be).
* build-aux/mk-octave-config-h.sh: Add missing flag to octave-config.h.
