Reproducing an unexpected behavior in zig. The current state prints

COLORS: 0

If line 8 in main.zig is commented in, it prints

COLORS: 256

Tested in iTerm2 on macOS 10.15.4.

compile & run

zig build-exe --library ncurses main.zig && ./main

    // const pCLRS = &c.COLORS;

    if (nc.COLORS) |clrs| {
