 # rpmbuild wrapper that translates "--with[out] FEATURE" into RPM macros
 #
 # Unfortunately, at least recent versions of rpm do not support mentioned
 # switch.  To work this around, we can emulate mechanism that rpm uses
 # internally: unfold the flags into respective macro definitions:
 #
 #    --with[out] FOO  ->  --define "_with[out]_FOO --with[out]-FOO"
 #
 # $(1) ... WITH string (e.g., --with pre_release --without doc)
 # $(2) ... options following the initial "rpmbuild" in the command
 # $(3) ... final arguments determined with $2 (e.g., pacemaker.spec)
 #
 # Note that if $(3) is a specfile, extra case is taken so as to reflect
 # pcmkversion correctly (using in-place modification).
 #
 # Also note that both ways to specify long option with an argument
 # (i.e., what getopt and, importantly, rpm itself support) can be used:
 #
 #    --with FOO
 #    --with=FOO
