["Manuel Bouyer" <bouyer%netbsd.org@localhost>]

Module Name:    pkgsrc
Committed By:   bouyer
Date:           Thu Feb  4 23:51:51 UTC 2021

Modified Files:
        pkgsrc/sysutils/xentools413: distinfo
Added Files:
        pkgsrc/sysutils/xentools413/patches:
            patch-.._seabios-rel-1.12.1_src_string.c

Log Message:
When compiling with -fwhole-program gcc will omit functions which
are not used in the file, even if not declared static.
Add __attribute__((externally_visible)) to memcpy() to force gcc to
include it.
Fixes build on -current (gcc 9)
This is a build fix so no PKGREVISION bump
