	11	05 Jan 08 SHL Move from arccnrs.c and comp.c to here
[920]	12	06 Jan 08 GKY Add NormalizeCmdLine to check program strings on entry
[985]	13	29 Feb 08 GKY Changes to enable user settable command line length
[1699]	14	15 Oct 08 GKY Fix NormalizeCmdLine to check all 5 executable extensions when no extension provided;
[1394]	15	use searchapath to check for existance of file types not checked by DosQAppType;
[1761]	16	close DosFind.
[1439]	17	28 Jun 09 GKY Added AddBackslashToPath() to remove repeatative code
[1480]	18	12 Jul 09 GKY Add xDosQueryAppType and xDosAlloc... to allow FM/2 to load in high memory
[1545]	19	23 Oct 10 GKY Add ForwardslashToBackslash function to streamline code
[1632]	20	17 Sep 11 GKY Fix commandline quoting issues
[1750]	21	01 Mar 14 JBS Ticket #524: Made "searchapath" thread-safe. Function names and signatures were changed.
[1761]	22	So calls to these functions had to be changed.
	23	21 Mar 14 SHL Add IsAbsolutePath
