Syntax error in '#if 1'

[SlipCore]

Test example:

struct stage_info stages[] =
{
    [0] = {
        .type = &stage_test_type,
        .conf = &(struct stage_test_conf) {
#if 1
            .mode = 0,

#endif
        }.base,
    },
}

Getting error: Syntax error in #if [preprocessorErrorDirective] in simple #if 1 directive:

Checking test.c ...
test.c:6:0: error: Syntax error in #if [preprocessorErrorDirective]
#if 1

It can be fixed with parentheses: #if (1)

There are many places in the our sources with such conditional preprocessor directives without parentheses, but the syntax error does not occur in all cases.
