-current's /usr/include/sys/lwp.h causes compile problems in pkgsrc

[Markus W Kilbinger <mk%kilbi.de@localhost>]

Hi!

-current's actual /usr/include/sys/lwp.h produces problems when
compiling several pkgsrc packages, e. g. pkgsrc/www/seamonkey:

  cc -o prsystem.o -c -fvisibility=hidden   -I/usr/pkg/include -I/usr/include 
-I/usr/pkg/include/python2.5 -I/usr/X11R7/include 
-I/usr/X11R7/include/freetype2 -O2 -I/usr/pkg/include -I/usr/include 
-I/usr/pkg/include/python2.5 -I/usr/X11R7/include 
-I/usr/X11R7/include/freetype2 -ansi -Wall -pthread -O2 -fPIC -DPIC  -UDEBUG  
-DMOZILLA_CLIENT=1 -DNDEBUG=1 -DHAVE_VISIBILITY_HIDDEN_ATTRIBUTE=1

-D_PR_PTHREADS -UHAVE_CVAR_BUILT_ON_SEM -D_NSPR_BUILD_ 
-I/usr/obj/pkg/www/seamonkey/work.x86_64/comm-1.9.1/mozilla/dist/include/nspr 
-I../../../pr/include -I../../../pr/include/private  prsystem.c

                   from prsystem.c:62:
  /usr/include/sys/lwp.h:200: error: expected '=', ',', ';', 'asm' or

Anybody knows how to solve this?

Markus.
