# The Automake BUILT_SOURCES hook ultimately calls
# construct_dictionary.py to generate both pmix_dictionary.h and
# pmix_dictionary.c.  However, in a parallel "make" invocation, this
# script could be executed twice simultaneously, which *could* lead to
# the generated pmix_dictionary.* files being corrupted (i.e., two
# invokcations simultaneously writing to these generated files).  To
# prevent that from happening, force this one Makefile to be run
# serially via the .NOTPARALLEL target.  This has two side-effects:
#
# 1. construct_dictionary.py will only be invokved once, because since
#    both targets are created in the first invocation, make won't need
#    to invoke it a second time for the second target.  This is both
#    expected and good.
# 2. There is a (very) minor performance implication for the
#    other make steps in this Makefile.am (i.e., they won't be run in
#    parallel).  But this simple solution to avoid a devious potential
#    file corruption issue is an acceptable tradeoff.
