Subject: Eliminate 'unreferenced formal parameter' compiler warning in msvc_dbg
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8dad87955e30b01bdae2a9b8eee2cbd7b321b482;p=gc

Eliminate 'unreferenced formal parameter' compiler warning in msvc_dbg

* extra/msvc_dbg.c (GetDescriptionFromAddress): Cast format argument
to void.
* extra/msvc_dbg.c (GetDescriptionFromStack): Pass format argument to
GetDescriptionFromAddress (instead of NULL).
