Subject: * cygtls.h (_cygtls::retaddr): New method.
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=cda353552a76334b1fd86c0407ec763c7d7cfc81;p=pf3gnuchains%2Fpf3gnuchains3x.git

* cygtls.h (_cygtls::retaddr): New method.
* dll_init.cc (cygwin_detach_dll): Use new tls function to find return address
since this function is now signal guarded.
(update_envptrs): Remove unneeded braces.
* syscalls.cc (statvfs): Coerce full_path to avoid a gcc warning.
