	Amounts to new C files, new htcontext and httexexec.  Fingers crossed.

1998-10-22  Eli Zaretskii  <eliz@is.elta.co.il>

	* tex4ht.c [__DJGPP__] (ANSI, DOS_GIF_FILE): Define.
	(LSTAT): Define to stat for every system that doesn't define
	S_ISLNK.
	(WRITE_BIN_FLAGS, READ_BIN_FLAGS): Use binary mode with DJGPP.
	(dos_file_names): New variable.
	[WIN32] (sigint_handler): Add missing semi-colon in prototype
	declaration.
	(sig_err): If got fatal signal other than SIGINT or SIGQUIT, don't
	return to caller, since the program will be aborted otherwise.
	(search_file_ext): Allow use of both forward- and back-slashes on
	DOS and Windows platforms.
	(insert_ch) [DOS_GIF_FILE]: Only use butchered file name if long
	file names aren't supported (dos_file_names is TRUE).
	(main) [KPATHSEA]: If input is from stdin which is not a console
	device, switch it to binary mode.  Set dos_file_names to TRUE for
	all DOS platforms, FALSE on Unix and WIN32, and compute at runtime
	for DJGPP.  Simplify logic of finding the init file by pushing
	HOME=C: into environment if $HOME isn't defined on DOSISH systems.
	Only use butchered file names for GIF files if long file names
	aren't supported (dos_file_names is TRUE).

Mon Feb 16 13:16:07 1998  Sebastian Rahtz  <s.rahtz@elsevier.co.uk>

	not $texmf/tex/generic/tex4ht
	* tex4ht.c: use "other text files" search path instead of TEXINPUTS

Mon Feb  2 11:32:03 1998  Sebastian Rahtz  <s.rahtz@elsevier.co.uk>
