#261 dynamic call problem

[ToutEnMasm]

Dynamic declare:
;-------- sprintf_s PROTO C :DWORD ,:DWORD ,:DWORD , :VARARG -------------------------
EXTERNDEF ADRsprintf_s:DWORD ;sprintf_s use a vararg en couldn't be call in the library
Psprintf_s TYPEDEF PROTO C :DWORD ,:DWORD ,:DWORD , :VARARG
Fsprintf_s TYPEDEF PTR Psprintf_s
sprintf_s TEXTEQU <Fsprintf_s ptr ADRsprintf_s>

.code
.LISTALL
invoke sprintf_s,addr sz_buffer,sizeof sz_buffer,write("Friendlyname : %s"), addr buffer
invoke o_printcrlf,addr sz_buffer
.NOLIST

result with ml OK:

will be fixed in v2.10.

It is preferable to provide simple assembly source as test case. Disassembly listings are only useful in rare cases, when there's a code generation issue.
