Hi all,

    I've built a program that uses an assembly based wrapper to install
hardware
interrupt handlers. The program compiled just fine under djgpp 2.02. I then
got
djgpp latest version (2.03) and despite the program still working ok I get
a strange warning every time I compile : "Indirect ljmp without '*'" in my
AS wrapper file.
Here's a portion of the affected code (inspired from the allegro irqwrap.s
file) :

---------------------------------------------------------------------
#define WRAPPER(x)                                                         ;
\
.globl __irq_wrapper_##x
; \
.align 4
; \

; \
__irq_wrapper_##x:
; \

/* wrapper code */
...
iret

/* MAX_IRQ wrappers defined */
WRAPPER(0);                          /* each of these lines reports the
above warning */
WRAPPER(1);
WRAPPER(2);
WRAPPER(3);
WRAPPER(4);
WRAPPER(5);
WRAPPER(6);
WRAPPER(7);

.globl __irq_wrapper_0_end    /* To calculate function size */
.align 4
__irq_wrapper_0_end:
   ret
---------------------------------------------------------------------

    Can someone help me and explain me what is happening? Thanks in advance.
