[lsb-discuss] LSB 3.2 Compliance Report: Sun JRE 6 (update 5) on x86

[Wichmann, Mats D]

Sorry to send these piecemeal. 

dl_iterate_phdr is used to workaround a bug in "old"
dladdr.  According to the comments, this workaround
could be removed once the minimum requirement is
moved forward to glibc 2.3.x (in the LSB context, that's
already been a requirement for a long time).

gnu_get_libc_version and gnu_get_libc_release are
used as a fallback for confstr(_CS_GNU_LIBPTHREAD_VERSION)
which is also not in LSB; these are used to try to
make a determination between LinuxThreads and NPTL.
Again in current LSB context this is not an issue
since NPTL is required.  Note that in a non-glibc
situation (say, mobile with a different libc), the
nptl question may not be as definitively answered.

pthread_getattr_np is used even though Java considers
it buggy so it has to have some special workarounds.
these are only in arch-specific Linux pieces.

sysinfo is used to determine available memory:
sysinfo(&si);
return si.freeram * si_mem_unit;

I'm not sure why this can't use the sysconf
_SC_AVPHYS_PAGES call instead but there's probably
a valid reason.

Note that *all* of this stuff is in the hotspot
subdirectory tree.

there are sendfile references outside this area,
but it's hard to tell what gets included in which
flavor of build.
