If the build system really needs to know which compiler version it's
using I would much rather we have the user tell it that in their
CONFIG_SITE.Common.win* file(s). The build system has to run any kind of
per-compiler test every time it reads a Makefile, and calling out to a
Perl script to do this kind of test every time is probably going to slow
the build measurably.

On the other hand doing this kind of thing using the pre-processor and a
#pragma optimize() setting is fast and localized, so I would much prefer
that we stick with that solution if it can do what we need. You can tell
whether you're building a dynamic binary there by the presence of the
EPICS_BUILD_DLL macro.
