New submission from David Shao <[e-mail]>:

pkgsrc gstreamer0.10 fails to build on
DragonFly  2.7-DEVELOPMENT DragonFly v2.7.0.4.g63c2a-DEVELOPMENT #11: Mon M=
ar 29
07:30:32 PDT 2010     root@:/usr/obj/usr/src/sys/X86_64_GENERIC  x86_64

due to default gcc 4.1.2 not being able to handle code similar to that from
/usr/pkgsrc/multimedia/gstreamer0.10/work/gstreamer-0.10.28/gst/gstutils.c:

#include <inttypes.h>
#include <stdio.h>

int main(void)
{
  __uint128_t num =3D 1000;
  __uint128_t denom =3D 10;
  __uint128_t res =3D num / denom;
  printf("Result =3D %ju\n", (uintmax_t)res);=20
  return 0;
}

$ gcc div128.c
/tmp//ccHUakkJ.o: In function `main':
div128.c:(.text+0x39): undefined reference to `__udivti3'
$ CCVER=3Dgcc44 gcc -Wall -Werror div128.c
$ ./a.out
Result =3D 100

Using CCVER=3Dgcc44 before pkgsrc bmake allows gstreamer0.10 and thus xfce4=
 to
build and run on x86_64.
