Thats pretty awesome.
So if anyone else is willing to join in a challange, I have an example
first steps piece of C that uses the azul interfaces to attempt to grab
a blob of
memory.

I was expecting my code to not work for the printf, however it does not
actually seem to do the mreserve
Anyone want to join my insanity ?

My question (probably one of many to irritate and annoy all the
fine folks here) would be, is there a sensible way to compile into
pypy a small amount of C code that can be used to bootstrap and
bridge some esoteric c libraries into pypy, the code that I want
to run, on startup of pypy would be the following

It's not annoying at all, we use it in strategic places.
For example, see how pypy/rlib/_rffi_stacklet.py implements a
stacklet C library that can be used in RPython.
It uses an "ExternalCompilationInfo" (eci) object:
- separate_module_files lists the .c files you want to compile and link
- separate_module_sources is an easy way to embed C snippets (each
source will create a .c file)
Then you can use rffi.llexternal with "compilation_info=eci"
to declare a function defined in this library.
