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
103 # library search path. This cause many builds to fail.

1008 # sometimes the function call is _llseek or something) and steal the 2nd
1009 # parameter. here is an example:
1010 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
