   | 12376   | Bug #253336 - Set PORTAGE_VERBOSE=1 so that files are        |
   | zmedico | displayed as they are merge.                                 |

   | 12377   | Fix the 'Unrecognized configure options' check for           |
   | zmedico | compatibility with output produced by Autoconf 2.63. Thanks  |
   |         | to Arfrever Frehtes Taifersar Arahesis for reporting.        |

   | 12378   | Inside action_sync(), when running as root, detect if        |
   | zmedico | $PORTDIR has non-root uid/gid bits and drop privileges to    |
   |         | match the existing bits if appropriate.                      |

   | 12379   | Bug #253467 - Don't allow alien $A values to leak into the   |
   | zmedico | ebuild environment.                                          |

   | 12380   | When dropping privileges inside action_sync(), set the umask |
   | zmedico | to preserve the group write bit if appropriate.              |
