This is trickier than I thought -- it's not the GC after all.  In my configure
script for Snd, autoconf defines _FILE_OFFSET_BITS to 64 if large files are implemented.
The config.h "include" precedes everything else.  When scm_getc is called
within guile, it thinks sizeof(scm_t_port) is 92.  Everything is fine until
my skip comment procedure is called (with this 92 byte struct) -- it
thinks the scm_t_port size is 104, and fields like rw_active (in scm_getc
which is apparently expanded inline) are not where it expects them to be!
If I undef _FILE_OFFSET_BITS, both agree on the struct size, and there
is no problem.
