// NMAKE.C - main module
//
// Copyright (c) 1988-1990, Microsoft Corporation. All rights reserved.
//
// Purpose:
// This is the main module of nmake
//
// Revision History:
// 01-Feb-1994 HV Move messages to external file.
// 15-Nov-1993 JdR Major speed improvements
// 15-Oct-1993 HV Use tchar.h instead of mbstring.h directly, change STR*() to _ftcs*()
// 10-May-1993 HV Add include file mbstring.h
// Change the str* functions to STR*
// 26-Mar-1992 HV Rewrite filename() to use _splitpath()
// 06-Oct-1992 GBS Removed extern for _pgmptr
// 08-Jun-1992 SS add IDE feedback support
// 08-Jun-1992 SS Port to DOSX32
// 29-May-1990 SB Fix precedence of predefined inference rules ...
// 25-May-1990 SB Various fixes: 1> New inference rules for fortran and pascal;
// 2> Resolving ties in timestamps in favour of building;
// 3> error U1058 does not echo the filename anymore (ctrl-c
// caused filename and lineno to be dispalyed and this was
// trouble for PWB
// 01-May-1990 SB Add predefined rules and inference rules for FORTRAN
// 23-Apr-1990 SB Add predefined rules and inference rules for COBOL
// 20-Apr-1990 SB Don't show lineno for CTRL+C handler error
// 17-Apr-1990 SB Pass copy of makeflags to putenv() else freeing screws the
// DGROUP.
// 23-Feb-1990 SB chdir(MAKEDIR) to avoid returning to bad directory in DOS
// 02-Feb-1990 SB change fopen() to FILEOPEN()
// 31-Jan-1990 SB Postpone defineMAcro("MAKE") to doMAke(); Put freshly
// allocated strings in the macro table as freeStructures()
// free's the macroTable[]
// 24-Jan-1990 SB Add byte to call for sprintf() for "@del ..." case for /z
// 29-Dec-1989 SB ignore /Z when /T also specified
// 29-Dec-1989 SB nmake -? was giving error with TMP directory nonexistent
// 19-Dec-1989 SB nmake /z requests
// 14-Dec-1989 SB Trunc MAKEFLAGS averts GPF;Silently ignore /z in protect mode
// 12-Dec-1989 SB =c, =d for NMAKE /Z
// 08-Dec-1989 SB /NZ causes /N to override /Z; add #define TEST_RUNTIME stuff
// 01-Dec-1989 SB Contains an hack #ifdef'ed for Overlayed version
// 22-Nov-1989 SB Changed free() to FREE()
// 17-Nov-1989 SB defined INCL_NOPM; generate del commands to del temps
// 19-Oct-1989 SB ifdef SLASHK'ed stuff for -k
// 04-Sep-1989 SB echoing and redirection problem for -z fixed
// 17-Aug-1989 SB added #ifdef DEBUG's and error -nz incompatible
// 31-Jul-1989 SB Added check of return value -1 (error in spawning) for -help
// remove -z option help message
// 12-Jul-1989 SB readEnvironmentVars() was not using environ variable but an
// old pointer (envPtr) to it. In the meantime environ was
// getting updated. Safer to use environ directly.
// 29-Jun-1989 SB freeStructures() now deletes inlineFileList also
// 28-Jun-1989 SB changed deletion of inline files to end of mainmain() instead of
// doMake() to avoid deletion when a child make quits.
// 19-Jun-1989 SB modified .bas.obj to have ';' at end of cmd line
// 21-May-1989 SB freeRules() gets another parameter to avoid bogus messages
// 18-May-1989 SB change delScriptFiles() to do unlink instead of calling
// execLine. Thus, ^C handling is better now. No more hangs
// 15-May-1989 SB Added /make support; inherit /nologo
// 13-May-1989 SB Changed delScriptFiles(); added MAKEDIR; Added BASIC rules
// Changed chkPrecious()
// 01-May-1989 SB Changed FILEINFO to void *; OS/2 Version 1.2 support
// 17-Apr-1989 SB on -help spawn 'qh /u nmake' instead. rc = 3 signals error
// 14-Apr-1989 SB no 'del inlinefile' cmd for -n. -z now gives 'goto NmakeExit'
// CC and AS allocated of the heap and not from Data Segment
// 05-Apr-1989 SB made all funcs NEAR; Reqd to make all function calls NEAR
// 27-Mar-1989 SB Changed unlinkTmpFiles() to delScriptFiles()
// 10-Mar-1989 SB Removed blank link from PWB.SHL output
// 09-Mar-1989 SB changed param in call to findRule. fBuf is allocated on the
// heap in useDefaultMakefile()
// 24-Feb-1989 SB Inherit MAKEFLAGS to Env for XMake Compatibility
// 22-Feb-1989 SB Ignore '-' or '/' in parseCommandLine()
// 16-Feb-1989 SB add delScriptFiles() to delete temp script files at the
// end of the make. Also called on ^c and ^break
// 15-Feb-1989 SB Rewrote useDefaultMakefile(); MAKEFLAGS can contain all flags
// now
// 13-Feb-1989 SB Rewrote filename() for OS/2 1.2 support, now returns BOOL.
// 3-Feb-1989 SB Renamed freeUnusedRules() to freeRules(); moved prototype to
// proto.h
// 9-Jan-1989 SB Improved /help;added -?
// 3-Jan-1989 SB Changes for /help and /nologo
// 5-Dec-1988 SB Made chkPrecious() CDECL as signal() expects it
// main has CDECL too; cleaned prototypes (added void)
// 30-Nov-1988 SB Added for 'z' option in setFlags() and chkPrecious()
