9 Portability problems fixed by Gnulib:
12 This function crashes when invoked with invalid arguments on some platforms:
15 On platforms where @code{off_t} is a 32-bit type, @code{fstat} may not correctly
16 report the size of files or block devices larger than 2 GB.
17 (Cf. @code{AC_SYS_LARGEFILE}.)
20 Portability problems not fixed by Gnulib:
23 @xref{sys/stat.h}, for general portability problems with @code{struct stat}.
25 On Cygwin, @code{fstat} applied to the file descriptors 0 and 1, returns
26 different @code{st_ino} values, even if standard input and standard output
27 are not redirected and refer to the same terminal.
