First, there is a bug with .o files that declare large static arrays/data 
structures.  See a simple test case posted to the news group at the end of 
this message (I checked that test case: it indeed won't link with ld from 
Binutils 2.5.2).

Then there is the case of large libraries.  Maybe it's a good idea to ask 
on the news group that people who had these problems contact you and send 
you examples of such libraries, so you could check.  (I don't have any 
examples of such libraries.)  You can also use the mail-archives to 
search for such posts and contact people that complained about these 
problems.

There is also a need to teach Binutils to know about DJGPP stubbed 
executables.  This is not a bug, but it prevents e.g. `strip' to be able 
to strip a stubbed executable, so you need to exe2coff-strip-stubify.

Trying to convince a friend of mine to use DJGPP, I try to compile the
following, in essai.c :
#include <stdio.h>
unsigned char Tableau[1024L*1024L*16L];

int main(int argc, char * argv[])
{
printf("hello world\n");
return(0);
}

(In french "Tableau" means "array", and "essai" means "try")

It compiles fine, but does not link : I got the folowing :
e:/miko/trash/essai.o : could not read symbols : Bad value.

If I reduce the size of the array to 1024*1024*15, the linking is OK.
So my question : is there a maximum length for a static array ?
Curiously my computer has 16 M of memory : is there a connexion ?
