NetBSD iws-50.cambridge 3.0_RC5 NetBSD 3.0_RC5 (GENERIC) #0: Wed Nov 30 23:39:30 UTC 2005  builds@b3.netbsd.org:/home/builds/ab/netbsd-3-0-RC5/cobalt/200511302123Z-obj/home/builds/ab/netbsd-3-0-RC5/src/sys/arch/cobalt/compile/GENERIC cobalt
>Description:
The package devel/pcre v6.4nb1 (from a pkgsrc tarball dated December 3, 03:35) will not build on a Cobalt Qube 2 due to duplicate trait definitions.
>How-To-Repeat:
cd /usr/pkgsrc/devel/pcre
make
>Fix:
Remove the #include <type_traits.h> lines from pcre_stringpiece.h.  The following patch fixes the build, but has not been tested on any other ports:
