Request for swapcontext and getcontext to be ported to our libc

[Petr Janda]

Just letting you know that mtasker now compiles after 
buildworld/installworld. Though, wip/powerdns-recusor doesnt compile yet 
(a new error), not mtasker related.

pdns_recursor.cc: In function `void startDoResolve(void*)':
pdns_recursor.cc:563: error: invalid conversion from `void*' to `char*'
pdns_recursor.cc:564: error: invalid conversion from `void*' to `char*'
pdns_recursor.cc:1139: confused by earlier errors, bailing out
[wrapper.sh] note: The real command line, after the pkgsrc wrapper, was:
/usr/obj/pkgsrc/wip/powerdns-recursor/work/.gcc/bin/g++ -O -pipe 
-I/usr/obj/pkgsrc/wip/powerdns-recursor/work/.buildlink/include -Wall 
-O3 -c -o pdns_recursor.o pdns_recursor.cc 
-L/usr/obj/pkgsrc/wip/powerdns-recursor/work/.buildlink/lib
gmake: *** [pdns_recursor.o] Error 1
*** Error code 2

If someone could please take a look at it, I would be very happy.

You can find the source changes and a tiny test program here:

I hope to have a libc-only implementation completed before the end of
      
the
  
week.
      
Libc and kernel compiled, but wip/powerdns-recursor still gives me the
mtasker errors.
    
I'm assuming that you did installworld/installkernel/reboot before
attempting to build wip/powerdns-recursor.
After a bit of searching, I added the wip/ bits to my pkgsrc installation
and have found that powerdns-recursor has compile warnings/errors/ICE on
DFly that are totally unrelated to the *context functions.
I'm curious to know what patches/tweaks you are using in your environment to
get to the point where you see *context-related failures.
