 This bug report is for FreeBSD 9.  It is NOT patched.
 
 The m4 command malfunctions in 8.x for any x and 9.y for any y.  The
 documentation nevertheless continues to mention 3 arguments for the eval
 functions.  It is not a bug that the 2nd and 3rd arguments are ignored;
 there is simply no code in m4 that attempts to implement that
 functionality.
 
 Please, please either fix eval to honour 3 arguments, or document it in
 m4's man page as accepting just 1 argument for 8-STABLE and 9-STABLE.
 
 (As things stand now, No FreeBSD release or snapshot work for me on
 Haswell: The m4 bug makes releases inappropriate, kernel panics make
 amd64 FreeBSD 10 prereleases unusable, and clang bugs make i386 FreeBSD
 10 prereleases unusable...)
