[1299]22 24 Nov 08 GKY remove redundant code and minor speed up of Stubby
[1358]23 25 Dec 08 GKY Add ProcessDirectoryThread to allow optional recursive drive scan at startup.
24 25 Dec 08 GKY Add DRIVE_RSCANNED flag to monitor for the first recursive drive scan per session
[1471]25 to prevent duplicate directory names in tree following a copy before initial scan.
[1400]26 08 Mar 09 GKY Additional strings move to PCSZs in init.c
[1482]27 13 Dec 09 GKY Fixed separate paramenters. Please note that appname should be used in
28 profile calls for user settings that work and are setable in more than one
29 miniapp; FM3Str should be used for setting only relavent to FM/2 or that
30 aren't user settable; realappname should be used for setting applicable to
31 one or more miniapp but not to FM/2
[1498]32 17 JAN 10 GKY Changes to get working with Watcom 1.9 Beta (1/16/10). Mostly cast CHAR CONSTANT * as CHAR *.
