Bug#186299: workaround for php3 compilation
The file pack.c compiles fine with -O0. Obviously the build process tries this, but the -O0 gets overwritten by -O1.

Bug#164872: Partial patch for _GNU_SOURCE bug in g++-3.2
This is a partial patch for the _GNU_SOURCE bug in g++-3.2. It does not fix everything, but it will cause a simple "Hello, world" program to compile. I am working on fixing other headers. This patch is in the public domain. It comes "as is" with *absolutely no warranty*. fdc2f6871d40d5bbbc8656541a8425c0 *c++.patch -- Brian M.
