commit ddfb842637997554b16d6a427bb77fd679050c1c
Author: Peter Rosin <address@hidden>
Date:   Wed Jun 16 14:13:43 2010 +0200

    Wrap some MSVC options in the compile script.
    
    * lib/compile: MSVC supports naming the output file, the option
    is just not called -o, so transform -o into the appropriate form
    for MSVC. Also wrap some other options while at it (-L, -l, -Wl,
    -Xlinker and -I) and convert paths to windows form where needed
    for those options to make MSVC more usable in an autotooled
    environment.
    * doc/automake.texi (Auxiliary Programs): Document the above
    extension of the compile script.
    * NEWS: Updated.
