The special "-" parameter can be used in a macro declaration to request that no argument processing be done by RPM and that the raw argument list shall be passed to the macro for further processing instead.

Example:

rpm --define '%foo(-) %{*}' --eval '%foo 5 a -z -b2'

should now print "5 a -z -b2" (previously, it would fail with an "error: Unknown option").

As a RPM macros maintainer, I want be able to define parametric macros which opt out of option processing, so that I can backport a macro from Fedora that uses this feature.

This should work:

$ rpm --define 'mymacro(-) ... %{?**}' --eval '%mymacro -a'
... -a

As it currently does not work with rpm-4.16.1.3-34.el9:

$ rpm --define 'mymacro(-) ... %{?**}' --eval '%mymacro -a'
mymacro: invalid option -- 'a'
error: Unknown option a in mymacro(-)
