# 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 cman)
# $(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
