Subject: Remove a gcc-4.5 compilation warning:
X-Git-Tag: android-x86-4.4-r1~1143^2~8^2~50
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=506b13d910a1a603b29fbc5a9ba41ba4c533b14c;p=android-x86%2Fbionic.git

Remove a gcc-4.5 compilation warning:
bionic/libc/include/../include/stdlib.h: In function 'int grantpt(int)':
bionic/libc/include/../include/stdlib.h:138:23: warning: parameter '__fd' set but not used [-Wunused-but-set-parameter]

By adding __attribute((unused)) to __fd, the warning is gone, and this
attribute is compatible with gcc-4.4.0, gcc-4.3.1 gcc-4.2.1.
There is no any side effect.
