The change isn't Solaris-specific, btw. I've just compiled the same
preprocessed file (with -fpermissive added to avoid
/vol/gcc/src/hg/trunk/reghunt/libstdc++-v3/libsupc++/new:93:54: error:
'operator new' takes type 'size_t' ('long unsigned int') as first parameter
[-fpermissive]
) on x86_64-unknown-linux-gnu: with gcc 4.6 off the top of the 4.6
branch, the symbol doesn't occur in the output at all, with mainline, it
does.
