Whats the consensus on alloca and it's presence in libc? Gcc will internally
deal with calls to this normally and it's only in libc for some archs:

./i386/gen/alloca.S
./m68k/gen/alloca.S
./ns32k/gen/alloca.S
./vax/gen/alloca.S
./arm/gen/alloca.S
./x86_64/gen/alloca.S

This means on say powerpc machines libc doesn't have alloca which makes some
package ports "interesting" when configure/etc go looking for alloca.

Is there any reason to leave these?
