Subject: [PATCH] fix attr malloc error with recent glibc/gcc
Recent GCC has support for __attribute__((__malloc__)) with arguments, but clang
does not. castxml uses clang internally. And recent glibc/gcc uses the attribute
with arguments. Mix all this, and you get:
error: '__malloc__' attribute takes no arguments
when compiling itk with python wrapping.
To fix this, we add a define to castxml flags to remove the extra arguments.
