Gnulib module: ---
Portability problems not fixed by Gnulib:
@itemize
+@item
+This function uses the effective id instead of the real id on some
+platforms:
+Cygwin 1.5.x.
+@end itemize
+
+Other problems of this function:
+@itemize
+@item
+There is an inherent race between calling this function and performing
+some action based on the results; you should think twice before trusting
+this function, especially in a set-uid or set-gid program.
+@item
+This function does not have an option for not following symbolic links
+(like @code{stat} versus @code{lstat}). If you need this option, use
+the Gnulib module @code{faccessat} with the @code{AT_EACCESS} flag.
