Hi!

Looking into body of X11 dlls compiled on NT and W95, I see one difference 
- arrays of zeroes in NT compiled dll and random bytes in the same place in 
W95 compiled dlls... Is it the cause of troubles with X11 dlls compiled on 
95?

It seems to me it's because of difference in handling file seeks on NT and 
W95:

#include <stdio.h>
#include <fcntl.h>

main()
{
	int i=1;
	int fd;

	fd=open("test", O_WRONLY | O_CREAT | O_BINARY, 0666);
	write(fd, &i, 1);
	lseek(fd, 0x2b7, SEEK_SET);
	i++;
	write(fd, &i, 1);
	lseek(fd, 0x400, SEEK_SET);
	i++;
	write(fd, &i, 1);
}

When running this program on NT, output file contains all zeroes and bytes 
1, 2 and 3 in desired file positions. But when running on W95, file 
contains garbage and desired bytes in desired positions.

Geoffrey, probably there is a bug in bfd or ld - they make a seek to fill a 
portion of a file with zeroes, this seeks results in zeroes on unixes and 
NT, but in random contents on W95!
