Cannot run tests for functions with C99 features not permitted in C++ [BUG]

[Lana243]

Description If source file contains C99 feature not permitted in C++, then no generated tests can be run.

To Reproduce Steps to reproduce the behavior:

1. Generate tests for the following function:

int sum_sign_9_11_static(int a[static 9][11]) {
    int sum = 0;
    for (int i = 0; i < 9; i++) {
        for (int j = 0; j < 11; j++) {
            sum += a[i][j];
        }
    }
    if (sum == 0) {
        return 0;
    } else if (sum > 0) {
        return 1;
    } else {
        return -1;
    }
}

2. Run test:

TEST(error, sum_sign_9_11_static_test_1)
{
    int a[2][11] = {{0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}};
    sum_sign_9_11_static(a);
}

Expected behavior Generated test runs correctly.

Actual behavior The following error occurred:

static array size is a C99 feature, not permitted in C++
static int sum_sign_9_11_static(int a[static 9][11]) {

Moreover, if there are another correct tested functions in the source file, tests for them also cannot be run as source file cannot be compiled.
