+- Bug #1163325:  Decimal infinities failed to hash.  Attempting to

 - Bug #1160802: can't build Zope on Windows with 2.4.1c1.  The
   ``MSVCCompiler`` class in distutils forgot to record that it was
   initialized, and continued adding redundant entries to the system
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
