Subject: Eliminate 'this statement may fall through' GCC warnings
X-Git-Tag: v8.0.0~484
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=07feeaa568096c917bb61d69dde79e6a2511cf3f;p=platform%2Fupstream%2Flibgc.git

Eliminate 'this statement may fall through' GCC warnings

* cord/cordprnt.c (extract_conv_spec): Eliminate fall through in
a switch statement.
* cord/tests/de.c (do_command): Replace "fall through:" comment with
"FALLTHRU" formal comment (on a new line).
* win32_threads.c [!GC_PTHREADS && !GC_NO_THREADS_DISCOVERY]
(GC_DllMain): Likewise.
