>Description:
	Building the musicpd package from pkgsrc-2018Q4 on a NetBSD 8
	system gives the following error:

../src/util/Compiler.h:66:6: error: #error Sorry, your gcc version is too old. You need at
 least version 6.0.
 #    error Sorry, your gcc version is too old.  You need at least version 6.0.

Makefile:GCC_REQD+=             4.9

>How-To-Repeat:
	On a NetBSD 8 system "cd .../pkgsrc/audio/musicpd; make"
>Fix:
	Change GCC_REQD to "6" as per the patch below.  Note that
	on HEAD musicpd has been updated to a newer version and has
	this same GCC_REQD change.  The patch below is _only_ for
	pkgsrc-2018Q4.
