[flext] CPU usage problem

[Patrick Gampp]

Hi,
I try to rebuild flext with MSVC 2012. I selected PD Debug and get the 
following error when compiling fltimer.cpp. Does anyone know, what the 
problem is here?

It also says at source\fltimer.cpp(51) "Error: Class "TimerVars" may
not have a template argument list.

Cheers, Patrick
