It's good style within OpenBSD to have system headers before userland. Also we don't try to have one mega header that includes everything, that should be up to the source files. If you propose a patch that works for Darwin, Ill be happy to check it on OpenBSD.

Our gcc4 would error out with -Wall about missing sentinel in function call.
This fixes it.

Ill turn it off that way, as our GCC4 insists on those sentinels being present in the function call.

We wrote our own pkg-config in perl and it resides in the base system. We could change it to provide such a file.

I don't think this is appropriate to apply, then; info gcc says:

     A valid `NULL' in this context is defined as zero with any pointer
     type.  If your system defines the `NULL' macro with an integer type
     then you need to add an explicit cast.  GCC replaces `stddef.h'
     with a copy that redefines NULL appropriately.

so if OpenBSD's gcc packaging breaks this, please complain to your gcc maintainer.

If you really can't use the normal pkg-config then you should make sure your reimplementation is compatible, I think. In the C implementation, there is actually no pkg-config.pc - pkg-config inserts equivalent information into its internal data structures before reading any .pc files. I'd recommend doing the same.

Note that the 0.21 dependency is to support a fairly subtle feature of Requires.private (adding private dependencies' CFLAGS), so you may need to check that your pkg-config reimplementation behaves the same.

We try to have our pkg-config implementation as compatible as possible with the "normal" one, I've added the missing feature our pkg-config, and the diff is awaiting review and further testing. So the pkg-config are not needed anymore, thanks for pointing it out.

Indeed.
