mdj pushed a commit to branch stable-2.2
in repository guile.

commit d9af6706e8a1a0148d492b222758e49e03d225b7
Author: Mikael Djurfeldt <address@hidden>

    Bootstrap optimization
    
    * bootstrap/Makefile.am: Build both eval.go and psyntax-pp.go before
      the rest of the .go files so that they are handled by a fast macro
      expander. This saves time for a parallel build.
