Subject: Work around MinGW's macro definition of 'interface' to 'struct'
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4083a06092adf7132de7c94e763fd5cd29e5e302;p=clang

Work around MinGW's macro definition of 'interface' to 'struct'

Previous attempts to rename the IBOutletCollection argument to something
other than "Interface" were undone (r127127 and r139620).  Instead of
renaming it, work around this in tablegen, so the public facing getter
can have the usual name of 'getInterface'.

Fixes PR26682
