* 22586: Src/parse.c, Src/utils.c: minor warnings spotted
|
||||
on Cygwin: unnecessary static declaration in parse.c, typo in
|
||||
set_widearray, also comments on other warnings that are harder
|
||||
to avoid.
|
||||
|
||||
* 22585: makepro.awk, Src/utils.c: zsh.exports was missing
|
||||
VA_ALIST declarations and some multibyte-related stuff.
