/*** globals.c - global variables/needed across modules ************************
*
* Copyright (c) 1988-1990, Microsoft Corporation. All rights reserved.
*
* Purpose:
* This is the routine in which global variables reside.
*
* HackAlert:
* The functionality explained in the Notes below work only because of the way
* Microsoft Compiler's upto C6.0A allocate initialized data ... in the order
* in which it is specified. All variables between startOfSave and endOfSave
* have to be initialized. According to ChuckG this functionality is not
* guaranteed in C7.0 and so these should be moved to a struct.
*
* Notes:
* This module was created for an interesting reason. NMAKE handles recursive
* calls by saving its global variables somewhere in memory. It handles this by
* allocating all global variables which have value changes in each recursive
* in adjacent memory. The routine called recursively is doMake() and before it
* is called the address of this chunk of memory is stored. When the recursive
* call returns the memory is restored using the stored address. startOfSave and
* endOfSave give the location of this chunk. The reason this method was opted
* for is that spawning of NMAKE would consume a lot of memory under DOS. This
* might not be very efficient under OS/2 because the code gets shared.
*
* Revision History:
* 15-Nov-1993 JR Major speed improvements
* 04-Apr-1990 SB Add fHeapChk
* 01-Dec-1989 SB Made some variables near and pushed some into saveArea
* 19-Oct-1989 SB variable fOptionK added (ifdef SLASHK)
* 02-Oct-1989 SB add dynamic inline file handling support
* 18-May-1989 SB Support of H and NOLOGO in MAKEFLAGS
* 24-Apr-1989 SB Added ext_size, filename_size, filenameext_size &
* resultbuf_size for OS/2 1.2 support
* 05-Apr-1989 SB made revList, delList, scriptFileList NEAR
* 22-Mar-1989 SB removed tmpFileStack and related variables
* 16-Feb-1989 SB added delList to have scriptfile deletes at end of make
* 21-Dec-1988 SB Added scriptFileList to handle multiple script files
* removed tmpScriptFile and fKeep (not reqd anymore)
* 19-Dec-1988 SB Added fKeep to handle KEEP/NOKEEP
* 14-Dec-1988 SB Added tmpScriptFile to handle 'z' option
* 30-Nov-1988 SB Added revList to handle 'z' option
* 23-Nov-1988 SB Added CmdLine[] to handle extmake syntax
* made pCmdLineCopy Global in build.c
* 21-Oct-1988 SB Added fInheritUserEnv to inherit macros
* 15-Sep-1988 RB Move some def's here for completeness.
* 17-Aug-1988 RB Declare everything near.
* 06-Jul-1988 rj Ditched shell and argVector globals.
