101 # in some cases when linking dynamic, the .a in /usr/lib is used
102 # instead of the .so in /lib due to gcc/libtool tweaking ld's

1009 # sometimes the function call is _llseek or something) and steal the 2nd
1010 # parameter. here is an example:
1011 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek

1013 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
