From: corinna Date: Fri, 2 Dec 2011 16:15:25 +0000 (+0000) Subject: * Makefile.in (cygpath.exe): Add -luserenv to ALL_LDFLAGS. X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=9940b7ce3a4562d4e340fc3a7a21e8a0caf43037;p=pf3gnuchains%2Fpf3gnuchains4x.git * Makefile.in (cygpath.exe): Add -luserenv to ALL_LDFLAGS. * cygpath.cc: Throughout, use cygwin_conv_path WIN_W rather than WIN_A conversion. (get_long_path_name_w32impl): Remove. (get_long_name): Drop pre-Windows 2000 accommodations. Just call GetLongPathNameW here directly. (get_special_folder): Convert first parameter to WCHAR buffer pointer. Drop conversion of result from WCHAR * to char *. (do_sysfolders): Accommodate change to get_special_folder and only convert result to char * last. Drop pre-Windows 2000 accommodations and just call GetProfilesDirectoryW directly. Replace call to GetWindowsDirectoryW with call to GetSystemWindowsDirectoryW. Just call GetShortPathNameW directly. (do_pathconv): Simplify buffer handling. --- diff --git a/winsup/utils/ChangeLog b/winsup/utils/ChangeLog index edb551aaa4..f3d597777d 100644 --- a/winsup/utils/ChangeLog +++ b/winsup/utils/ChangeLog @@ -1,3 +1,20 @@ +2011-12-02 Corinna Vinschen + + * Makefile.in (cygpath.exe): Add -luserenv to ALL_LDFLAGS. + * cygpath.cc: Throughout, use cygwin_conv_path WIN_W rather than WIN_A + conversion. + (get_long_path_name_w32impl): Remove. + (get_long_name): Drop pre-Windows 2000 accommodations.
