 Summary of the bug:

 Building ffmpeg in MSYS2 / MinGW32 with GCC 8.2.0 and Perl 5.28.0-1, the
 configure step fails for ffnvcodec: Texinfo/Parser.pm complains about a
 deprecated "unescaped left brace in regex".

 How to reproduce:

 I let the media-autobuild_suite compile ffmpeg, which updates MSYS2 before
 updating all used libraries to their last revisions (except for cases
 where a specific revision is required due to bugs).

 An archive of log files is attached to this report. The last error
 messages displayed are:
