I recently picked up the MozillaBuild environment for Windows, based on MSYS. Unfortunately, I find the version of CVS to have a couple bugs in it which are ruining the experience - bugs which were fixed a long time ago in CVS. Specifically, the :
pserver:username:password@domain bug (fixed in CVS version 1.11.1) and the broken pipe signal bug (fixed in CVS version 1.11.13).
MSYS is apparently providing CVS version 1.11.
