patch2 darwin & libgcj

Sat Dec 29 09:12:00 GMT 2001

Hi,
this is #2 to get libgcj 'compile' under darwin.
I'm not completely happy with, since I don't know the correct cast, see
below. Also, to apply this patch you have to run autoconf & autoheader
in gcc/libjava to get the new introduced AC_STRUCT_TIMEZONE propagated correctly.
This patch introduces a new configure.in check versus timezone. Darwin
doesn't know tzname so I tried to play.
The two patches make libgcj compile under darwin (ufs) although I have
some linking errors.
I send these patches to gcc-patches since it is noted so and they are
not mainly java related.
Comments welcome for improvements!!
Andreas
P.S, I don't send the configure diff since I'm not sure about it. Do I
have to provide this or is anyone else able to update it?
P.S2, here I'm completely unsure could someone help, I don't know the
definition of tzname:
tzinfo = &tim->tm_zone
