[cc65] Possible bug in cc65

I've been working on a cartridge libary for cc65's C64 platform and have been encountering problems with one of the demos.� I converted a part of the demo to run outside the demo (i.e. in the normal configuration) and found the same two bugs; 1. cputsxy() displays garbage text and; 2.�the output for rand() is too regular.� I have the code here:
�
----------------------
blot.c
----------------------
static const unsigned char blotc [4]={0,1,2,5};
void blot ()
{
�static unsigned i;
�_randomize ();
�bordercolor (3); bgcolor(1); textcolor (0);
�clrscr ();
�for (i=0; i<20*40; ++i) {revers (rand()&1); cputc(' ');}
�revers(0);
�cputcxy (0,24,"Press any key to continue...");
�//gotoxy (0,24); cputs ("Press any key to continue...");
�while (!kbhit());
�cgetc();
}
void colorblot ()
{
�static unsigned i;
�_randomize ();
�bordercolor (3); bgcolor(1); textcolor (0);
�clrscr (); revers(1);
�for (i=0; i<20*40; ++i) {textcolor (blotc[rand()&3]); cputc(' ');}
�revers(0);
�textcolor (0);
�gotoxy (0,23);
�puts ("Press any key to continue...");
�while (!kbhit());
�cgetc();
}
----------------------
main.c
----------------------
void blot ();
void colorblot ();
void main()
{
�bgcolor (1); bordercolor (2); textcolor (5);
�clrscr();
�blot(); colorblot();
}
----------------------
I used cc65 v. 2.13.3, SVN 5495 to compile the code.
