Subject: Moved some function decls, a struct, and a #define from regexp.h into here.
X-Git-Tag: 0_46~78
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=268b8c4f387b9019bbb3591fb07403925d55d0c5;p=platform%2Fupstream%2Fbusybox.git

Moved some function decls, a struct, and a #define from regexp.h into here.
Also static-ified said functions so they do not have namespace conflicts with
the libc regex functions.
