* config.bat (mvOk): Protoize. (djgppOk): Include sys/version.h for _DJGPP_MINOR. * lisp/loadup.el: If system-type is ms-dos, dump bootstrap-emacs as b-emacs.dmp. * msdos/INSTALL: Document new versions of tools that have been verified successfully to compile Emacs. * msdos/emacs.djl: New linker script that arranges to link symbols in `.subrs' in a contiguous part of data, as the DJGPP runtime appears to treat any non-data and non-text section as allocatable. * msdos/mainmake.v2 (install): Install emacs.dmp alongside emacs.exe. * msdos/sed1v2.inp (CFLAGS): Define to -O2 -g3. (LDFLAGS): Provide the said linker script. (HAVE_PDUMPER): Define to yes. (UNEXEC_OBJ, PAXCTL_dumped, PAXCTL_notdumped): Delete. (DUMPING): Set to pdumper. (MAKE_PDUMPER_FINGERPRINT): Don't erase this variable. Don't stubify or set minstack. Remove native-comp specific directives. Don't remove temacs prior to copying and replace `pdmp' extension with DOS-conformant `dmp'. * msdos/sed2v2.inp (HAVE_UNEXEC): Remove definition. (HAVE_PDUMPER): Define to 1. * msdos/sed6.inp (top_srcdir): Define appropriately. * msdos/sedlibmk.inp (HAVE_BLKCNT_T): Define to 1. * src/emacs.c (load_pdump) [MSDOS]: Use `dmp' suffix. * src/pdumper.c (Fdump_emacs_portable) [MSDOS]: Replace ".pdmp" suffixes with ".dmp".
