27 * Revision 1.10 1998-10-19 15:24:20 adam
28 * New nmem utility, nmem_transfer, that transfer blocks from one
31 * Revision 1.9 1998/10/13 16:00:17 adam
32 * Implemented nmem_critical_{enter,leave}.
34 * Revision 1.8 1998/07/20 12:35:59 adam
35 * Added more memory diagnostics (when NMEM_DEBUG is 1).
37 * Revision 1.7 1997/10/31 12:20:08 adam
38 * Improved memory debugging for xmalloc/nmem.c. References to NMEM
39 * instead of ODR in n ESPEC-1 handling in source d1_espec.c.
40 * Bug fix: missing fclose in data1_read_espec1.
