That's strange for 2 reasons :
- this is a macro that defines another symbol
- the program wouldn't link or start if the symbol was not accessible

I added GST_EXPORT to the GST_CAT_DEFAULT declaration. But the defined

many of them)

I'll commit that part (as soon as I verified that it works on Linux too).
