   This is ridiculous,  I have installed djgpp, just recently.  I can
   compile code, justfine, but when I try to run anything, including the
   standard "Hello Wolrd" program it crashes.

   This is my simple code:

   #include <stdio.h>

   main()
   {
     write("Hello World\n");
   }

   I compile it as such:  gcc -o hello.exe hello.c

   and this is what happens when I execute it:

   C:\stuff\djgpp>hello
   Exiting due to signal SIGSEGV
   General Protection Fault at eip=00001bdb, error=a030
   eax=ffffffff ebx=0004c0c0 ecx=00000000 edx=00000000 esi=00000054
   edi=00009ad4
   ebp=00049acc esp=00049ab4 cs=00a7 ds=00af es=00af fs=0087 gs=00bf
   ss=00af
   Call frame traceback EIPs:
     0x00001bdb
     0x000000af

   C:\stuff\djgpp>

   this must be something stupid.  Please help.

OK.  This looks suspiciously like DJGPP V1.  Before I tell you to get V2...
V1 produces COFF a.out files only.  You then have to prepend the GO32 DOS 
extender.  Try this:

	gcc -o hello hello.c
	coff2exe hello
	hello

OK, now.  Get DJGPP V2.  Version 1.xx is no longer supported.  V2 no longer 
requires its own DOS extender but uses any DPMI 0.9+ server for Protected mode 
services.  You can even download one of several free DPMI servers, CWSDPMI and
PMODE/DJ to name two.  The V2 compiler can generate .exe format files directly.

To download go to either DJ's web site (http://www.delorie.com/) or:

ftp://ftp.coast.net/SimTel/vendors/djgpp/v2/readme.1st
ftp://ftp.coast.net/SimTel/vendors/djgpp/v2/
ftp://ftp.coast.net/SimTel/vendors/djgpp/v2gnu/
ftp://ftp.coast.net/SimTel/vendors/djgpp/v2tk/
ftp://ftp.coast.net/SimTel/vendors/djgpp/v2misc/

Get the readme.1st file first, it lists the files you NEED and the ones you 
will WANT and how to install.
