Comment (by kencu):

 the aligned memory functions I added to legacysupport…using a newer gcc
 would be unexpected to find them without it.

 the usual fix for this:
 {{{
 error: ‘for’ loop initial declaration used outside C99 mode
 }}}

 is simply to enable C99 mode…the gcc-4.2 compiler defaults to c89, but
 gcc7 defaults to C11 so you could use that to get c99 mode if you can’t
 figure out how to get std=c99 onto the build line. MacPorts dislikes that
 kind of fix, as you know.

 but have to actually try it to see what happens, of course.
