I'm using some code in my programs which need
the following code at the beginning:
int _crt0_startup_flags = _CRT0_FLAG_NEARPTR | _CRT0_FLAG_NONMOVE_SBRK;

As soundroutine I use the MIDAS soundsystem
which already sets this startup flags...so I get an error
if redefine them. So, what should I change in my code
for using it without the crt0_startup_flags  ?
If I remove the flags it will crash.

code which uses crt0_startup_flag, otherwise it will crash:

int mode;
int bpp,xres,yres;

  __dpmi_regs regs;
  __dpmi_meminfo mem;
  ...
  mem.size = yres*xres*(bpp+1);
  mem.address = modeinfo.PhysBasePtr;
  __dpmi_physical_address_mapping(&mem);

  addr=mem.address;
  video_pointer = (unsigned char *)(addr + __djgpp_conventional_base);
  vid_point = (unsigned short *)video_pointer;
*** Note: this pointers make problems without
the startup flags
