Gnulib module: fopen
This function does not fail when the file name argument ends in a slash
and (without the slash) names a nonexistent file or a file that is not a
directory, on some platforms:
-HP-UX 11.00, Solaris 9, Irix 5.3.
+HP-UX 11.00, AIX 7.1, Solaris 9, Irix 5.3.
+@item
+On platforms where @code{off_t} is a 32-bit type, @code{fopen} may not work
+correctly with files larger than 2 GB. (Cf. @code{AC_SYS_LARGEFILE}.)
@item
On Windows platforms (excluding Cygwin), this function does usually not
recognize the @file{/dev/null} filename.
