Use proper macro conditional negation syntax in the manual
Historically only %{!?foo} syntax has been used, the reversed ?! version
was only introduced in 0d75ef1e0a0609ee61386f02fa311d6d8ac79450 (perhaps
accidentally) and should not be used, much less recommended.
(cherry picked from commit 7b0b5e7d2cf53817ec5e2545c5f591a26db72cec)

Syntax ``` %{?macro_name:value} -%{?!macro_name:value} +%{!?macro_name:value} ``` can be used for this purpose. `%{?macro_name:value}` is expanded to "value" if "macro_name" is defined, otherwise it is expanded to the empty string. -`%{?!macro_name:value}` is the negative variant. It is expanded to "value" +`%{!?macro_name:value}` negates the test. It is expanded to "value" if `macro_name` is not defined. Otherwise it is expanded to the empty string. Frequently used conditionally expanded macros are e.g. Define a macro if it is not defined: ``` -%{?!with_python3: %global with_python3 1} +%{!?with_python3: %global with_python3 1} ``` A macro that is expanded to 1 if "with_python3" is defined and 0 otherwise: |
