 read the manual about fixincludes and #include_next

 Name the wrappers differently.

 Could you please explain why it isn't a bug?  It IS breaking a bunch of
 our code.  We have to "wrap" the system header, so we have our own (that
 includes the "real" header).
 
 To help me work around this (not a bug) feature, could you explain (a
 little ) what happens to cause this (not a bug) behavior?
 
 your solution of not doing it isn't practical in this case.  Thanks.

Compiling above causes an error (g++ -c foo.c)

while
#include <unistd.h>
extern "C" int access(const char *, int);

does not.  For some reason the C++ front end treats quoted includes differently than bracketed ones.

compile the above code snippets and the error should present itself.
