Subject: [PATCH] * doc/c-tree.texi: Update information about
flag_honor_std. * doc/install.texi: Note that binutils is required on
HPUX 11. * doc/invoke.texi (-fhonor-std): Note that -fno-honor-std is
now the default.
* config/mips/abi64.h (RETURN_IN_MEMORY): Fix handling of
variable-sized types.
* lang-options.h: Emit documentation for -fno-honor-std, not
-fhonor-std.
