Compiler Pickyness by Default
=============================

If you are building PMIx from a Git clone (i.e., there is a
``.git`` directory in your build tree), the default build includes
extra compiler pickyness, which will result in more compiler warnings
than in non-developer builds and will mandate that warnings be
treated as errors.  Getting these extra compiler warnings
is helpful to PMIx developers in making the code base as clean as
possible.

Developers can disable this picky-by-default behavior by using the
``--disable-picky`` configure option.  Also note that extra-picky
compiles do *not* happen automatically when you do a VPATH build
(e.g., if ``.git`` is in your source tree, but not in your build
tree).

Prior versions of PMIx would automatically activate a lot of
(performance-reducing) debugging code by default if ``.git`` was found
in your build tree.  This is no longer true.  You can manually enable
these (performance-reducing) debugging features in the PMIx code
base with the ``--enable-debug`` configure option.
