static and inline functions

Hit a problem when compiling a library. The problem is with mixing static and inline functions, which is not allowed by the standard, but is allowed by gcc. Example code looks like:

char \* c;

static void foo(char \*);

inline void work()
{
  foo(c);
}

void foo(char\* c)
{
} 

When this code is compiled it generates the following error:

% cc s.c
"s.c", line 7: reference to static identifier "foo" in extern inline function
cc: acomp failed for s.c

It turns out that there is a workaround for this problem, which is the flag -features=no%extinl. Douglas Walls describes the issue in much more detail.
