Subject: Re: [OMPI users] mpicc -showme:compile output (possible bug report)

What exactly does mpicc --showme:compile output?

mpicc (and friends) typically do not output -I only for "special"
directories, such as /usr/include, because adding -I/usr/include may
subvert the compiler's normal include directory search order.
