Jonas Maebe 3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

{ Stack size used to be 256 K under BeOS. So, it was the value
used in previous version of FPC for BeOS (but lost in the road
to 2.* ;-).
According to buildtools/gcc/gcc/config/i386/beos-elf.h in the
Haiku's repository, this value was increased to 1Mb since r4.1b3.
Under R5, this value is even greater. listarea report a default
size of 16 Mb for the user stack of the main thread.
People who still use BeOS nowadays should use R5 (or Haiku),
so i use this new value.
