glib/src/binding.hg: Export Glib::manage() [glibmm-2-66 branch]
Hi,
From the commit message
The newly-added function was missing a GLIBMM_API annotation, causing this function not to be exported. Fixes build of the glibmm binding test program on Visual Studio-style builds.
This function was added in commit f648c7fc.
With blessings, thank you!
