What I would like to do is to build a DLL which does not link to the C runtime
library (and therefore it does not have access to _alloca or other CRT functions).
The executable dynamically loads the DLL with dlopen() and the DLL calls
some callback functions provided by the executable. The DLL's size is about
20KB if it links to CRT, 8KB if it does not. The main motivation is to have
a small file.

So, is there a gcc option which allows not to call _alloca (even if the
performance is sub-optimal)?

Regards
Fabrizio
