bb_lai10.c 31-May-92 chh
bb_lai10.c 22-Apr-93 chh fix Reindex return value to AP.stat
--test raw speed using 32-bit long integer key, unique
1) this test uses a non-standard binary field as a sort field
2) this code is for raw speed tests--it's straight inline
Note: memory model must be medium, large, or huge
For Turbo C 2.0:
C>tcc -mm bc_lai10 BULLET.lib
For Quick C 2.50 (v2.50 *must not* use ATEXITXB (define QC250 to not)):
C>tcl -Am bc_lai10 BULLET.lib

Quick C uses a near _atexit for both medium and large standard LIBs
This is of course a bug! and it prevents the use of ATEXITXB. This
is with at least QC 2.50. If you experience a lock-up using ATEXITXB
then you know what the problem is. Easy enough to get a fix. Call MS.
And the problem is also in crt0dat. Turbo C operates correctly. */
