* lib/bitset.c (bitset_print): Don't assume size_t can be printed
with %d format.
* lib/ebitset.c (min, max): Undef before defining.
* lib/vbitset.c (min, max): Likewise.
* lib/subpipe.c (create_subpipe): Save local variables in case
vfork clobbers them.
* tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
error message syntax used by gcc-4.0.

debug_bitset): Use function prototypes; this removes the need for
declaring static functions simply to provide their prototypes.
Use size_t, not unsigned int, to count bytes.
(bitset_print): Use proper printf format for bitset types.
(bitset_next, bitset_prev, bitset_first, bitset_last):
Return BITSET_BINDEX_MAX (not -1) for no value,
since we now return the bitset_bindex type (not int).
