Subject: declared void functions as such
X-Git-Tag: flex-2-5-5b~498
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5afa7fe502544056f031f0672dcaf592baf95341;p=flex

declared void functions as such
prototypes for forward references
shuffled around some routines to make the order perhaps a little more logical
changed memory references to use void* instead of char*
