#248 tcl8.6.1 and itcl4.0.0,'Tcl_Var' issue

[Jojo]

We build tcl8.6.1 and its related package itcl4.0.0 using VS2005. While linking and building the newly generated dll tcl86t and itcl40t to our project we are getting the below mentioned errors.The header files included in our project are tcl.h,itcl.h,itclInt.h,itclIntDecls.h. Earlier configuration of our project was with tcl8.4.13 and itcl3.3 in which the linking and build was successful. Could you please let us know if we need to adapt something for this new tcl8.6.1 and itcl4.0.0?
