New issue 37 by jdswinb...@gmail.com: Not buildable with GCC 4.6
http://code.google.com/p/casacore/issues/detail?id=37
Casacore trunk (and presumably other versions) aren't buildable with GCC
4.6: see the log below. Building with GCC 4.5 is fine.
The relevant change from the GCC release notes
(http://gcc.gnu.org/gcc-4.6/changes.html) is "Most libstdc++ standard
headers have been changed to no longer include the cstddef header as an
implementation detail. Code that relied on that header being included as
side-effect of including other standard headers will need to include
cstddef explicitly."
The attached short patch gets things working for me.
