Subject: [bug #24009] does not check for short write()s

Follow-up Comment #5:

Hello!

This is now fixed:

  master ->
http://git.savannah.gnu.org/gitweb/?p=guile.git;a=commit;h=634aa8de8f8facc285867100c6c0a54c4ea5e6d4
  1.8 ->
http://git.savannah.gnu.org/gitweb/?p=guile.git;a=commit;h=b12a5fd7f645067143523094194db0154a890539

The version in `master' is more robust since it uses `full_write ()' from
Gnulib, which tries hard to actually write the given bytes; the fix in 1.8
does the minimum to make Glibc happy with `_FORTIFY_SOURCE=2'.

Most of the cases reported by `_FORTIFY_SOURCE' are when writing a single
byte to the signal pipe or the sleep FD.  In these situations, it would be
hard to handle a write/read error meaningfully, and it can't be very harmful
if one of these bytes is lost.

One last thing: the Flex-generated file `c-tokenize.c' does not check the
return value of `fwrite(3)', but there's nothing we can do here.  Another good
reason to not make `-Werror' the default?

Thanks,
Ludo'.
