The problem here is (most likely) that 'restrict' expands to something the
compiler doesn't understand.

But why is comment5.c including headers from gllib/ at all?
makemake.in is careful to distinguish native compilation (CC, CPPFLAGS, CFLAGS)
and cross-compilation (XCC, XCPPFLAGS, XCFLAGS). The values that configure
has determined are for the cross-compiler, i.e. for all source files that
include lispbibl.c or genclisp.h. These findings of configure do _not_
apply to the native compiler, that is used for compiling utils/comment5.c.
For this reason,
  - comment5.c must not include config.h,
  - comment5 must not be compiled with -I gllib,
  - comment5 must not be linked with libgnu.a.
If you follow this rule, you will not get an
"undefined reference to `rpl_malloc'".

makemake.in may surely need one or more tweaks to fulfil this separation
between native and cross compilations.
