 Keywords:            |       Port:  libgcc45
----------------------+----------------------
 Upgrading libgcc45 fails on macOS 10.12.6.  On macOS 10.13 there is an
 error that it is "not supported on macOS High Sierra and newer", however
 this is on macOS 10.12 Sierra where libgcc45 @4.5.4_14 works.  If it is no
 longer intended to work on Sierra then the error should be updated.
