Yes, I am talking about the last one of those two lines.

The reason I became aware of this change is a warning I get when
compiling an oct-file that uses an other library. This library also
uses fortran code and it also have an auto generated F77_FUNC_ macro,
the two macros are different, thus the warning.
Moving config.h away would silence the warning, and solve the problem
unless it was an important warning. But I don't know if it is, I know
too little about fortran linking, I was just curious about the change
in the macro.
