[OPEN-ILS-DEV] Testing Evergreen

[Scott McKellar]

I haven't tried Clang, but I tried splint a month or two ago.  I found it unusable for our C code because it expects local variables always to be declared before any executable statements in the same block.  E.g. it chokes on something like this:

int main( void )
{
    printf( "Hello, World!\n" );

    int rc = 0;
    return rc;
}

Our C code does this sort of thing a lot.  It's not kosher according to C89, but GCC accepts it without complaint.  I'm not sure what the C99 standard has to say on the subject.  In any case it's a useful language feature because it allows you to further limit the scope of your local variables.  It saddens me that splint doesn't like it.

I hope Clang isn't so finicky.
