9 Portability problems fixed by Gnulib:
12 This function mistakenly succeeds on pipes on some platforms: mingw.
14 This function produces incorrect results after @code{putc} that followed a
15 @code{getc} call that reached EOF on some platforms:
19 Portability problems not fixed by Gnulib:
22 This function produces incorrect results immediately after @code{fseek} on some
26 @code{fflush}, @code{ftell}, @code{ftello}, @code{fgetpos} behave incorrectly
27 on input streams that are opened in @code{O_TEXT} mode and whose contents
28 contains Unix line terminators (LF), on some platforms: mingw.
30 On platforms where @code{long} is a 32-bit type, @code{ftell} does not work
31 correctly with files larger than 2 GB. The fix is to use @code{ftello}
32 instead and to invoke the @code{AC_SYS_LARGEFILE} macro.
