Supporting such a prefix of course means that all section handling code ("var", "type", etc.) needs to respect the case of a "generic" token followed by "function", "procedure" or "class" and thus abort doing its own business.
Maybe I'll find the time somewhen in the future to rework the parser (plus scanner?) a bit so that code like this gets more easy to add and more importantly less ugly.

o made all (non-abstract) tdef and tsym constructors virtual
o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
class
o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
class from the base classes, and initialises the c*def/c*sym classes with
them. This is done so that the llvm target will be able to derive from
the tcpu*def/sym classes without umpteen ifdefs, and it also means that
the WPO can devirtualise everything because the c* variables are only
initialised with one class type
o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
calls

on the stack, this can be enabled by -OoFORCENOSTACKFRAME. This reduces the required
entry/exit code and makes an extra register available to the compiler. However, since this is
based on an estimation of the required stack size, it might have two drawbacks:
either the stack frame is estimated to big, the program requires a bigger stack than needed
or it is estimated too small, then the compiler throws an internalerror during compilation. These
issues can be overcome as soon as the compiler supports recompiling subroutines if needed.

functions whose implementation is declared "external". This results in less
efficient code (all calls will go through a stub), but it prevents interface
crc changes (-> no recompilations in case of circular dependencies) and it
also keeps the interface stable (if the external implementation is changed
afterwards to another external routine or to a local implementation, the
mangled name of the routine does not change) (mantis #24121)
