That C code won't work reliably outside of a lib$initialize section 
(for some settings), as the initialize psect is the only place where 
the settings reset can be done for some of what those pesky logical 
names control.

I've posted a block of BSD-licensed C code that has the initialize 
psect and the rest of the baggage within the NEWUSER source code 
<http://labs.hoffmanlabs.com/node/1260>; unlike Phillipe's, mine is 
entirely brute-force, but it also allows you to select the particular 
feature settings your code might require.
