I was chasing down why gettext wouldn't build and found CXX= : in one of
its generated Makefiles, and it turns out g++ can't see <cstddef> whilst
it *can* see <stddef.h>. gcc can also see <stddef.h>
Can anyone tell me in what way exactly my system is misconfigured, and
what I can do to make #include <cstddef> work?
[On my system, /usr/local is a symlink to /home/newdisk/usr-local, hence
the funny paths being visible.]
berndj@localhost:/tmp$ cat /tmp/foo.cpp
#include <stddef.h>
int main()
{
}
berndj@localhost:/tmp$ g++ -v /tmp/foo.cpp -o /tmp/a.out
