This is the reason why I often use tcc compiler for my edit/compile/hotreload cycle, it is about 8x faster than gcc with -O0 and 20x faster than gcc with -O2.
With tcc the initial compilation of hostapd it takes about 0.7 seconds and incremental builds are roughly 50 milliseconds.
The only problem is that tcc's diagnostics aren't the best and sometimes there are mild compatibility issues (usually it is enough to tweak CFLAGS or add some macro definition)
