Description

Quoting from the XLC++ 8.0 Compiler Reference, page 249 (-Q option):

To maximize inlining:

• for C programs, specify optimization (-O) and also specify the appropriate -Q options for the C language.
• for C++ programs, specify optimization (-O) but do not specify the -Q option.

We should review whether our use of -Q in optimized builds is called for.
