              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.
