27 * Revision 1.2 2000-02-28 11:20:06 adam
28 * Using autoconf. New definitions: YAZ_BEGIN_CDECL/YAZ_END_CDECL.
30 * Revision 1.1 1999/11/30 13:47:11 adam
31 * Improved installation. Moved header files to include/yaz.
33 * Revision 1.10 1998/10/19 15:24:20 adam
34 * New nmem utility, nmem_transfer, that transfer blocks from one
37 * Revision 1.9 1998/10/13 16:00:17 adam
38 * Implemented nmem_critical_{enter,leave}.
40 * Revision 1.8 1998/07/20 12:35:59 adam
41 * Added more memory diagnostics (when NMEM_DEBUG is 1).
43 * Revision 1.7 1997/10/31 12:20:08 adam
44 * Improved memory debugging for xmalloc/nmem.c. References to NMEM
45 * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
46 * Bug fix: missing fclose in data1_read_espec1.
