Follow-up Comment #1, bug #40150 (project mit-scheme):

I can find only a handful of lines where CFLAGS is touched at all, mostly to
add some -Wnitpick options (admittedly *after* CFLAGS, but so what?), or
override standard optimization options when configured with --enable-debugging
(the intention?).  Perhaps line 62 is all you meant; you were so...
unspecific.  Line 62 is only executed when ${GCC} is yes, but... maybe this
patch is all you need?
