47# 2.0.51, we now have support for installing libraries to lib32/lib64
48# to accomidate the needs of multilib systems. It's no longer a good idea
49# to assume all libraries will end up in lib. Replace any (sane) instances
50# where lib is named directly with $(get_libdir) if possible.

1088# sometimes the function call is _llseek or something) and steal the 2nd
1089# parameter. here is an example:
1090# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1091# lseek
1092# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
