Subject: * ebrowse.c (parse_qualified_param_ident_or_type): Make it clear
X-Git-Tag: emacs-pretest-24.0.90~104^2~275^2~726^2~1
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=6c0668d97b32ea806006ede9652d78d8aa2b62ce;p=emacs.git

* ebrowse.c (parse_qualified_param_ident_or_type): Make it clear

to reader (and to the compiler) that the loop always executes at
least once.  This prevents a warning with recent GCC.
