(Couldn't come with any better title)

I'm trying to convert a number of lines, like these: 

#define GENERIC_TYPE_METER_PULSE                     0x30 /*Pulse Meter*/
#define SPECIFIC_TYPE_NOT_USED                       0x00 /*Specific Device Class not used*/
......
#define MFG_ID_WAYNE_DALTON                          0x0008   //Wayne Dalton
#define MFG_ID_WILSHINE_HOLDING_CO_LTD               0x012D   //Wilshine Holding Co., Ltd
#define MFG_ID_WIDOM                                 0x0149   //wiDom
......
#define COMMAND_CLASS_ALARM                              0x71
#define COMMAND_CLASS_ALARM_V2                           0x71
#define COMMAND_CLASS_NOTIFICATION_V3                    0x71
#define COMMAND_CLASS_NOTIFICATION_V4                    0x71

in a file (c++) to something like these (for Java):

SPECIFIC_TYPE_NOT_USED((byte)0x00)             /*Specific Device Class not used*/
MFG_ID_WILSHINE_HOLDING_CO_LTD((byte)0x012D)   //Wilshine Holding Co., Ltd
COMMAND_CLASS_ALARM((byte)0x71)
....

I came up with this:

gawk '/^#define/ && / [[:xdigit:]]/ { printf "%s((byte)%s)\n",$2,$3 }'

but there are two issues - it doesn't work with awk; requires GNU-awk (gawk) and I also need the end-of-the-line comments in the output whenever available. How can I do that? I'm especially interested using awk but can live with sed as well. Cheers!!

$ cat tst.awk
/^#/ {
    hd[++nr] = sprintf("%s((byte)%s)", $2, $3)
    lgth = length(hd[nr])
    maxLgth = (lgth > maxLgth ? lgth : maxLgth)

    sub(/[^/]+/,"")
    tl[nr] = $0
}

END {
    for (i=1; i<=nr; i++)
        printf "%-*s%s\n", maxLgth+2, hd[i], tl[i]
}
$ awk -f tst.awk file
