Please is it possible to help me with submentioned program ?
I checked the FAQ200 and the online help with no results, maybe
overlooking something.

All is going well at compile time :

gcc -c -Wall -O2 err.c

But goes wrong at link time :

gcc -o err.exe err.o -lm

err.o :  could not read symbols : Bad value


When decreasing MAXLONG to 4194303 the linker accepted my program.
4194304 also seems a magic number :

4194304     = 2**22
4194304 * 4 = 2**24

and I suspect the linker not being able to handle vectors with a size
greater than 2**24 bytes.

I solved my problem with the non elegant way to declare several
vectors.
Is there another way to handle an huge array, I really need it ?
Please help.

I am using an i80486 66MHz with 8Mbytes RAM and 325Mbytes free
on the hard disk, DJGPP V2, gcc version 2.7.2 and CWSDPMI release 1
loaded with the -p switch and running windows95 restarted in dos mode.

The offending program err.c :

#define MAXLONG 4194304
int v[MAXLONG];
int i;
void main()
{
for(i=0;i<MAXLONG;i++)
{v[i]=i;}
}

Thanks in advance.
