commit c7732bd5add31b38fea113c9ab4ad4d97a0870c7
Author: Paul Smith <address@hidden>
Date:   Mon May 13 02:48:04 2013 -0400

    Add a new variable: GNUMAKEFLAGS
    
    This allows you to write portable makefiles that set GNU make-specific 
command
    line options in the environment or makefile: add them to GNUMAKEFLAGS 
instead
    of MAKEFLAGS and they will be seen by GNU make but ignored by other
    implementations of make.

commit 2627d8322136eac2b499dd12e2769eb01d7c74bc
Author: Paul Smith <address@hidden>
Date:   Mon May 13 02:17:29 2013 -0400

    Use level o_env_override for MAKEFLAGS so it's reset even with -e.
    
    Fixes Savannah bug #2216.

commit 381baeef7aa4f2c8758a9910ebb97af46c0dd7eb
Author: Paul Smith <address@hidden>
Date:   Mon May 13 01:30:24 2013 -0400

    Add new --trace[=MODE] flags, with --trace=dir
    
    This mode replaces the previous heuristic setting enabled with -O, where we
    would log directory enter/leave for each synchronized output.  Now we only
    do that if --trace=dir is given.
