Steve,

I should add that in R3.14.6 when you choose cygwin you get *both* the
cygwin toolset and also windows indirectly interface through the cygwin
POSIX emulating operating system wrapper. In future releases we hope to have
it so that these options may be chosen independently. 

That may be important because the channel access regression tests are
currently failing when run against the cygwin port of EPICS. They don't fail
against the native windows port. The EPICS system also appears to run much
more efficiently and probably also receives more accurate soft time when it
is interfaced directly to windows.

If you want to use the native windows port of EPICS, but you don't own or
otherwise want to use MS visual C++ then you could choose to install the
free Borland compiler, or another option would be to create new EPICS config
files so that there is an option where the cygwin gnu tools could be used to
build the native windows port of EPICS (that should work just fine).
