build problems with xulrunner 16.0.2: : 'malloc_usable_size' was not declared in this scope

[Richard PALO <richard.palo%baou.fr@localhost>]

Hello,

I"m trying to build xulrunner (for thunderbird and firefox) from trunk.
Running on OpenIndiana 151a7 in a non-global zone initially bootstrapped 
with Jonathan Perkin's bootstrap-2012Q3-illumos.tar.gz.

NB: gcc47 has been updated to 4.7.2 which is supposed to help mozilla 
builds...

the builds seem to indicate namespace problem:

g++ -o mozalloc.o -c   -DMOZ_GLUE_IN_PROGRAM -I../../xpcom -I. -I. 
-I../../dist/include  -I/opt/pkg/include/nspr -I/opt/pkg/include/nss/nss 
-I/opt/pkg/include/nss -I/opt/pkg/include/nspr        -fPIC

error: 'malloc_usable_size' was not declared in this scope
gmake[3]: *** [mozalloc.o] Error 1

has anybody else come across these and have any patches or other 
suggestions that may help?

I've tried the default, which is with mozilla-jemalloc, and also with 
mozilla-jemalloc disabled which gives a similar problem:

g++ -o mozalloc_abort.o -c   -DMOZ_GLUE_IN_PROGRAM -I../../xpcom -I. -I.
