#2872 error 2: Initializer element is not a constant expression (regression)

[Eric Rullens]

Since a while constructs such as

int i = (2 ? 3 : 4) + (2 ? 3 : 4);

const int j = (2 ? 3 : 4) + (2 ? 3 : 4);

are not accepted by SDCC anymore. I tried MCS51 and STM8 targets and both seem affected, although not in exactly the same way.

With older SDCC this was not an issue. Below some details on the versions. The attached a file contains the same information.

No issues are seen. Code compiles and resulting code is ok. (STM8 large model was not supported yet.)
