Is there an “alloca" like function in the RTL which allocates memory from the

No such function exists in FPC.
Is alloca something which is part of the OS or can this be implemented by
programmers or used from other libraries?
It compiler support for the allocation to actually happen on the stack.
When it's actually implemented in a library (rather than redirect to a
compiler intrinsic via a C macro), it will generally just allocate on
the heap instead.
