[gambit-list] When gsc makes gcc unhappy with symbol redefinitions

Bringing this up to the list, because this is an interesting output from
gsc and the file attachment feature of github doesn't work.
So I have this file which is the compiled output of gxc for srfi-14, with
some optimizations applied (namely inlining of struct ops in this case).
This results to gsc generating a bunch of cascading redefinitions, which
result in gcc warnings.

> gsc 14__0.scm
14__0.c:337:0: warning: "___SYM__3a_char_2d_set3224" redefined
 #define ___SYM__3a_char_2d_set3224 ___SYM(3,___S__3a_char_2d_set3224)

14__0.c:336:0: note: this is the location of the previous definition

So what's up with that?
