Can GCC ignore static declaration of a function?

Question

In my application I have a build config for pseudo unit testing (this is more a kind of manual debugging a dedicated function).

In those unit tests I'd like to access functions declared as static in their translation unit.

Is there an option of GCC that would allow me to call static functions from anywhere?

I'd like to avoid:

#if UNIT_TEST_MODE
void myfunction(void)
#else
static void myfunction(void)
#end
{
    // body
}

Everywhere!

Thanks for your help :).

There is not need to be verbose. Use a prefix define for every static function:

#if UNIT_TEST_MODE
#define UNIT_TEST_STATIC
#else
#define UNIT_TEST_STATIC static
#end

UNIT_TEST_STATIC void myfunction(void)
{
    // body
}

Another option is to move all static function from that .c file to a separate header. That header is included only in that .c file, but it can be included in the unit test .c file if needed. The functions will remain invisible in other files, unless the header is manually included.
(They will have to be defined as static inline. )
