i'm not sure how it should work but
__alloca is defined in libpcc using simple asm trickery
(modify stackpointer and the values on the stack and return)
so in case of pcc CFLAGS+=-Dalloca=__alloca works
tcc seems to implement alloca similarly in libtcc
but they call it alloca so no define is needed
glibc defines alloca as __builtin_alloca if gcc is used
for compilation otherwise it just provides an extern
declaration for it
