RESOLVED. Windows Server 2008 has Data Execution Prevention (DEP) enabled by default. Apparently there are a number of Cygwin programs that are not compatible DEP. All of the symptoms that I described are related to this. I've turned off DEP for all programs except crucial Windows applications.
I would prefer to make exceptions for Cygwin programs only, rather than turning off DEP for all third party applications; but the unix model of many small programs interoperating with one another would seem to make this impractical. I'll investigate that further, but as for the problem I described with my Cygwin installation on Server 2008 SP2, I've resolved it. Thanks for your patience.
