RE: Compilation errors with VC++ 6.0

["Pere Mato Vila" <Pere dot Mato at cern dot ch>]

Brian,

  This updated version works well. Thanks very much.
  I have a suggestion concerning the Windows installation. Would it be
possible to leave the DLL libraries (perhaps optionally) in the /lib of
the installation area. Copying them to the standard Windows location
(%WINDIR%/System32) is a problem when you have to work with several
versions since they have the same name. I know that it avoids to have to
set the right PATH but it makes very difficult to have centrally managed
installations.

tup.exe

which has DLL_EXPORT properly defined. It also adds an "extern" to
"__declspec(dllexport)".   Please let me know if this works better.
