it should get CFLAGS from the environment, if it doesn't it's a bug.

alloca allocates space on the stack, just like an automatic variable would.
of course malloc() can also be used, but then the allocated block must be
freed explicitly.

So it was used for simplicity, I didn't know it was not portable.

it is scsh aka scheme shell, you only need this if you change the class

can also link to it dynamically.

libc is linked dynamically.
