I am having trouble with gcc (emx version) and long filenames on
HPFS partition.

example :

#include <stdio.h>

void main()
{
FILE *f1,*f2,*f3,*f4;

	f1 = fopen ("this.file.already.exists","rb");
	f2 = fopen ("this_file_also_exists","rb");
	
	f3 = fopen ("this.file.should.be.created","wb");
	f4 = fopen ("so_should_this_file","wb");

	if (!f1)
	  printf ("\nUnable to open <this.file.already.exists>");

	if (!f2)
	  printf ("\nUnable to open <this_file_also_exists>");

	if (!f3)
	  printf ("\nUnable to create <this.file.should.be.created>");

	if (!f4)
	  printf ("\nUnable to create <so_should_this_file>");

	/** do some processing **/
	fcloseall();
}

The program prints out : 

	Unable to open <this.file.already.exists>

even (as the filename implies) it does exist. Also, instead
of creating the file 'this.file.should.be.created', it creates the
file 'this.fil.sho.be.cre'. The filenames that did not contain periods
were handled correctly.

The program was compiled with the command line :

gcc -o test.exe test.c

Then I tried the following compile commandline :

gcc -o test.exe test.c /emx/lib/io/open.c /emx/lib/sys/seterrno.c -los2

This time the program behaved correctly. Can anybody explain this ?
I assume that the I/O functions resides in the dll's, but I haven't
found out how to rebuild these. Anybody knows ?
