  Not many apps (source code) use these functions. Mainly MFC and 
ATL/WTL and derived applications.
If it is the later case (MFC/ATL) than one can just get native header 
together with where he gut MFC/ATL from, and just make sure that it is 
in a folder with higher precedence than wine's. It will compile.
  If your code can make do without MFC/ATL and only thing missing is CRT 
memory debugging tools, than you can go head and implement them. (Or use 
native msvcrtd.dll which is of the same license as crtdebug.h. Debug 
version is of a different license than release)
  What I've seen done by people is Leave these off, as wine is doing 
now, but use other (gcc type tools) compiled into wine to debug memory 
leaks. Was that Valgrind (http://valgrind.org/) or something? See list 
archives for instructions how to use it.
