Paul, if this kludge annoys you enough (I hope it will), please
suggest a cleaner way out of this conundrum.

configure.ac can define a macro that tells gmalloc.c about the kludge situation, and gmalloc.c can refer to that macro to decide whether to call rpl_free instead of plain 'free'.

Also, make sure that hybrid_free preserves errno.

Without these fixes some Gnulib code will possibly stop working, since the rest of Gnulib assumes 'free' preserves errno.
