Aaaargh! please STOP this nightmare. it is SOLVED and COMMITTED to 
CVS.

anyway just declaring 

  static int bmem_allowed;

clears it because our BSS is (should be?) cleared by the assembler
routines before calling C code. 
In this case, bmem is not allowed before bmem_init() has been called,
and after BDOS seizes the memory.
