Hefty is a good way to describe the output :-)

I understand there is no actual convention, but I am not clear on what information is required.  

If what you are looking for are -showme:compile, -showme:link, -showme or -show equivalents then we have nothing comparable.  -v is an  official option although the output is quite large.  

I took a look inside the mpCC script itself and it appears to have an environment variable MP_VERBOSE=YES.  Would it be possible for the auto configure to do something like:

bash-3.00$ export MP_VERBOSE=YES
bash-3.00$ echo "int main() { return 0; }" > t.C
bash-3.00$ mpCC t.C
xlC_r t.C -I/usr/lpp/ppe.poe/include -binitfini:poe_remote_main -lmpi_r -lvtd_r -lpthreads -L/usr/lpp/ppe.poe/lib/threads -L/usr/lpp/ppe.poe/lib -L/usr/lpp/ppe.poe/lib/ip
?

I can ask around to see about making the scripts more friendly although that may take sometime.
