Compiling webkit-gtk fails

[Marc Baudoin <babafou%babafou.eu.org@localhost>]

Hi,

Compiling webkit-gtk-2.4.8nb1 (from an up-to-date pkgsrc tree on
NetBSD/amd64 6.1.5) fails in the configure phase:

checking pthread.h usability... no
checking pthread.h presence... yes
configure: WARNING: pthread.h: present but cannot be compiled
configure: WARNING: pthread.h:     check for missing prerequisite headers?
configure: WARNING: pthread.h: see the Autoconf documentation
configure: WARNING: pthread.h:     section "Present But Cannot Be Compiled"
configure: WARNING: pthread.h: proceeding with the compiler's result
configure: WARNING:     ## -------------------------------------- ##
configure: WARNING:     ## Report this to http://bugs.webkit.org/ ##
configure: WARNING:     ## -------------------------------------- ##
checking for pthread.h... no
configure: error: pthread support is required to build WebKit
*** Error code 1

I had to recompile it after icu's update but the problem must
come from commits since 2.4.8 update (webkit-gtk-2.4.8 compiled
fine when it got out).

Anybody has the same problem?
