        It happen after any compilation

        Not, it doesn't.

        yes. I can launch windows without problem.

      Yes.

        it run well.

This is the message under windows,

go32/v2 version 2.0 built Jan 23 1996 22:03:02
Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2 binaries as
 well as v1 binaries (old makefiles).  Put ahead of the old go32 in your PATH.
DPMI memory available: 4520 Kb
DPMI swap space available: 37500 Kb


This is the message under MSdos

go32/v2 version 2.0 built Jan 23 1996 22:03:02
Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2 binaries as
 well as v1 binaries (old makefiles).  Put ahead of the old go32 in your PATH.

I have compiled this program,

#include <stdlib.h>
#include <dpmi.h>
#include <stdio.h>

void PrintFreeMem(void)
{ printf("Free Physical memory : %lu
Kbytes\n",_go32_dpmi_remaining_physical_memory()/1024);
  printf("Free Virtual  memory : %lu
Kbytes\n",_go32_dpmi_remaining_virtual_memory()/1024);
}

int main()
{ 
  PrintFreeMem();
}

With this Makefile
%%%%%%%%
CFLAGS = -g -Wall -O2 
AR = ar clq
AS = as
CC = gcc
CPP = cpp 
RM = del
RL = ranlib

.c.o:
	$(RM) $@
	$(CC) -c $(CFLAGS) $*.c

memo.exe: memo.o
	$(CC) memo.o  $(CFLAGS) -lpc -lm -o memo

%%%%%%
After that windows doesn't work. The computer is blockec and I have to
restart the computer.


-I have used DJGPP to compile the code generated by MATCOM, a Matlab to C++
Translator, but the problems increase. I have errors messages like

DPMI not supported .
Running under Windows an under MSDOS.
I tried to load the drives cwsdpmi, but the answer is the same.

 Any comment will be wellcome,
        Thanks in advance.
