I have tested this with Solaris 2.10 and GDB-7.1. I have removed 
the CANNOT_STEP_HW_WATCHPOINT define.  Here this bug does not occur.

    (gdb) start
    Temporary breakpoint 1 at 0x8050681: file watchp.c, line 13.
    Starting program: [...]/watchp

    Temporary breakpoint 1, main () at watchp.c:13
    13        myrec.x = 5;
    (gdb) print myrec.x
    $1 = 0
    (gdb) watch myrec.x
    Hardware watchpoint 2: myrec.x
    (gdb) s
    Hardware watchpoint 2: myrec.x
    
    Old value = 0
    New value = 5
    main () at watchp.c:14
    14        myrec.y = 3.4;


Here it works as expected.  GDB stops also at the other watchpoint.
So with "step" and "continue" both watchpoints are triggered, like
it behaves on x86-linux.
