C does not have this problem, because it does not have the possibility
to define functions in function scopes. Only applies to Pascal..

In C you have either absolute addresses (global/static scope) or
stack-relative addresses (function parameters / stack variables).

I have written a Pascal compiler for SPARC (single-pass code generation,
dual-pass assembly compilation) and a C compiler for a DSP (with a very
heavy backend optimizer/parallelizer with constant expression evaluation
and some other optimization stuff).
