    sysdeps/posix/tempname.c: Merge from gnulib
    
    Partial merge from gnulib which fixes a number of -Wundef warnings.
    The parts that differ from gnulib are the header comment, use of
    __glibc_unlikely, a #define of __secure_getenv and the use of tabs.
    The majority of the patch is cosmetic comment changes, the only runtime
    change is an abort if an unknown kind is passed to __gen_tempname.
    
    ChangeLog:
    
    2014-06-25  Will Newton  <will.newton@linaro.org>
    
    	* sysdeps/posix/tempname.c: Merge from gnulib, cosmetic
    	comment changes throughout the file.  Remove checks
    	for HAVE_*_H definitions that are not required.
    	(__gen_tempname): Call abort if an unknown kind value is
    	passed.
