Kerberos V5 for movemail, including detection of V4 and V5 header
files and libraries.
Include <string.h> when STDC_HEADERS is defined, to get
declarations of string functions.
[KERBEROS5] (socket_connection): Support the current MIT Kerberos
V5 API rather than the old one.
[KERBEROS] (socket_connection): Change a constant name from
SOCKET_ERROR to POP_SOCKET_ERROR to avoid a namespace conflict
with a constant in a header file.
(movemail.exe): Depend upon and link with getopt files.
(obj): Include new source files.
(FACE_SUPPORT, MOUSE_SUPPORT, FLOAT_SUPPORT, WINNT_SUPPORT): Define.
(lisp): Include new and reorganized elisp files.
New function new_pfnote will be used for "optimised tags", but
it depends on a constant that disables it for now.
New possibility of tagging global variables in C/C++/ObjC/Java
is enabled by default. Tags of member variables is disabled
by default. Options --(no-)members and --(no-)globals control them.
New symbol table entries for "import", "package" and "friend".
(Postscript_suffixes): .ps is Postscript.
(lang_names): Add Postscript.
(Postscript_functions): New function.
(TEX_decode_env): Close minor memory leak.
(just_read_file): Correct the char number of the tag.
since this causes some shells to generate the empty string when IFS is $nl.
(printlogline): Use SOH (octal code 1), not CR, since some PC-based shells
mishandle CR.
(struct linebuffer): New member `len' is the length of the string.
(find_entries, Pascal_functions, TeX_functions, TEX_getit):
Use it instead of strlen.
(TEX_getit): Declare and define unconditionally as static.
(TeX_functions): Use if instead of #if TeX_named_tokens.
(add_regex): Set RE_INTERVALS flag for regex compilation.
(substitute): Code cleanup.
(readline_internal): Code cleanup, set new member `len'.
(readline): Bug corrected.
* etags.c (xnew): Add support for debugging with chkmalloc.
(error): Use this instead of printf whenever possible.
(main): Only call xnew after having initialised progname.
(substitute): Bad memory corruption error corrected.
* etags.c (add_regex): Undo previous change.
(relative_filename): Small memory leak closed.
(absolute_filename): Cleaned up the code, possibly closing a bug.
(absolute_dirname): Always return a newly allocated string.
declarations.
(popmail, pop_retr): Since popmail always passes mbx_write and mbf
into pop_retr, there's no reason to pass in mbx_write, and the
file argument can be declared FILE * explicitly. This fixes a
compilation problem on systems with 64-bit pointers.
