Thank you for this report.
On Windows versions prior to Windows 7, GetPerformanceInfo is provided
by psapi.dll rather than kernel32.dll so psapi.dll would need to be
added to the link stage of the build on this OS.
I would expect MSVC 2010 on your system to automatically add this DLL to
the link stage of the build but it seems that you may have to do this
manually.
It is, of course, possible that this link failure is the result of an
issue in the MPIR code base but it looks more likely that it is an MSVC
2010 configuration issue.
If you can tarck it down to an MPIR issue, I will happily see if any
changes needed can be incorporated into MPIR.
with my best regards,
Brian
