Hy netlanders,
	please help me.


	Compiling a programm with the -xenix option I got problems
	with the regex and regcmp functions .
	This functions didn't work when compiled with the xenix option.
	I use a SCO/UNIX Version 3.2.2 . 
	I took the following program for testing the phenomena .


#include <stdio.h>

char *regcmp(char *,char *);
char *regex(char *,char *,char *);

main(argc,argv)
int argc;
char *argv[];
{
char ret[15];
char *m,*n;

        /* test if the name has an l or h at the beginning followed by a */
	/* number 							 */ 
	m = regcmp("\([lh][0-9]\{0,3\}\)$0",0);
	n = regex(m,argv[1],ret);

        /* show the the found part and the rest 			 */
	printf("\n	ret: %s n: %s \n",ret,n);

} /* end main */


	I got these results :
	=====================

	1)
	         cc -xenix -Zi -Od -o t_xenix t.c 

	-rwxr-xr-x   1 owner group      29445 Apr 24 09:14 t_xenix

	input/output: t_xenix h4444 -> ret:  n: (null)

	2)
	         cc -xout -Zi -Od -o t_xout t.c 

	-rwxr-xr-x   1 owner  group      29461 Apr 24 09:18 t_xout

	input/output: t_xout h4444 -> ret:  n: (null)

	3)
	         cc -x2.3 -Zi -Od -o t_x2.3 t.c 

	-rwxr-xr-x   1 owner  group      29445 Apr 24 09:17 t_x2.3

	input/output: t_x2.3 h4444 -> ret:  n: (null)


        The result shout be:
	====================
	input/output: t_x2.3 h4444 -> ret: h444 n: 4

	Does anybody know about the problem and know how to solve it ?
