// 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.
