  43 /* Changes are:
  44
  45 2007-05-21  Werner Koch  <wk@g10code.com>
  46
  47         * src/common/w32_account.c: New.
  48
  49         * src/common/w32lib.h: Undef "interface".
  50
  51 2005-11-17  Werner Koch  <wk@g10code.com>
  52
  53         Add boilerplate text to all files and explain legal status.
  54
  55         * w32_reg.c: Replaced g_free and g_strdup by regular C functions.
  56         (get_content_type_from_registry_with_ext): Ditto.
  57         * w32_dirent.c (readdir): Ditto.
  58         (opendir): Ditto.
  59         (closedir): Reformatted.
  60         (readdir): Reformatted, replaced use of g_strdup_printf and other
  61         g-style malloc function by regular ones.  Use DIR structure from mingw.
  62         * w32lib.h: Don't define finddata_t for mingw. Replaced replacement
  63         DIR structure by the one form mingw.  Allocate filename in dirent
  64         statically to match the defintion ussed by mingw.
  65         * w32_reg.c (read_w32_registry_string): Return error for invalid root
  66         key.
