{ 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.
