Whoops... I admit that we depend on a slightly older OpenJDK version,
and this time I didn't checked the latest code :) I just assumed it was

exactly :) I would like to make this test more sophisticated. I asked
for hints because of this:

The medialib code is more painful. I can sed it quickly (actually I
already did), question is, who need to define the correct constant? I
assumed the Makefile passing the define to the compiler? I hope those
definitions do not depend on something "inherited" by Solaris specific
headers for example.
So far we use a different build machinery, so I haven't looked at the
OpenJDK Makefiles yet.
I would do something like this, for LCMS, I would change the use of
_LITTLE_ENDIAN with __LCMS_LITTLE_ENDIAN, double underscore and LCMS
seems a nice define, then I'll try to get this upstream too.
To quote Kelly's mail (cross posting and cross mailing, I never did this
in my life before, wow :)

For the 300+ occurrences in OpenJDK, I would suggest
__OPENJDK_LITTLE_ENDIAN, or __JDK_LITTLE_ENDIAN. I need to fix this by
the end of the week anyway :(, so if you then like the patch, you only
have to take care of the internal defines.
I will not target OpenJDK6 though, I'm only interested in 7 so far
(speaking for my company, now).
