fix compile errors, fix revert-buffer bug on binary/Latin 1 files, Mule-ize some files
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-02-07 Ben Wing <ben@xemacs.org>
* emacs.c (make_argc_argv):
Cast to Wexttext * to fix compile error.
* nt.c (init_user_info):
Cast to CIbyte * to fix compile error.
* nt.c (open_unc_volume):
To fix compile error, store pathname into an Extbyte * variable
then write into the dest, casting to LPTSTR.
* emacs.c (debug_can_access_memory):
* fileio.c (Fmake_temp_name):
* fileio.c (a_write):
* fns.c:
* fns.c (check_losing_bytecode):
* fns.c (plists_differ):
* fns.c (internal_equal_trapping_problems):
* fns.c (base64_value_to_char):
* fns.c (base64_conversion_error):
* fns.c (STORE_BYTE):
* fns.c (vars_of_fns):
* lisp.h:
* nt.c (init_user_info):
* nt.c (mswindows_readdir):
* nt.c (mswindows_executable_type):
Replace raw `char *' or `unsigned char *' with characterized type --
Rawbyte, Binbyte, Boolbyte, Ibyte or Ascbyte. This should fix at
least one real bug -- in a_write(), the "speedy insert" code that
checks for an unchanged region declared the file data read in as
char[] but then compared the value to an Ichar. Hence, any chars
in the range 128-255 would always appear changed -- in particular,
this algorithm would fail completely with binary data.
