This is not a gcc question, as gcc does not provide the header files
or library code. This is a glibc or GNU/Linux question. You need to
ask somewhere else.
My general understanding is that you should not use <linux/...h>
unless you are writing kernel code. My general understanding is
although that msgbuf is not in SVID, although message queues are. But
I am not an expert, and I am quite likely wrong.
