mprec.h:297:1: warning: "_EXFUN" redefined


This is on a cygwin/winxp system... while building gcc trunk,
currently, and for quite some time, I have been getting this warning:

/usr/local/src/trunk/objdir/./gcc/xgcc
-B/usr/local/src/trunk/objdir/./gcc/ -B/usr/local/i686-pc-cygwin/bin/

/usr/include/_ansi.h:36:1: warning: this is the location of the
previous definition

Now, is this something to be concerned about and if so, in which
development forum would it be adressed?
