[TCLCORE] errno handling in core

[Zoran V. <zv...@ar...>]

Hi !

I'm new here (on this list)...

I did a grep on "errno" usage thru generic/* and found
some places where "errno" variable is handled directly,
i.e. w/o Tcl_GetErrno/Tcl_SetErrno wrappers. 
Shouldn't core use its own wrappers consistently? 

If yes, I can fix it (use wrappers)
If no, why?

Cheers,
Zoran
