Well, it seems that VC++ is generating the stack checking stuff. A web
search seems to reveal that this is only when "VC generates debug
code" (whatever this means). ;) So I'd say, switch VC to "release code
generation" (whatever that might mean) or just declare an Ada routine
called chkesp with C interface (well, "pragma Inline" won't work then,
I suppose).

BTW, according to

<URI:http://www.winehq.com/hypermail/wine-patches/2003/03/att-0132/01-msvcrt_chesp.diff>

the routine is contained in the msvcrt dll.
