:ADDPATCH fortran:

For
  character(len=1,kind=c_char) FUNCTION func() bind(c)

the C equivalent is:
  char func(void)

However, gfortran was passing the character as reference (older dump,
still contained the char length arguments):
   bar (__result, .__result, x, _x)

This patch fixes it.

Build and regression tested on x86-64. OK for the trunk?

Tobias

Yes, OK for trunk. Thanks!

Jerry
