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.
104 # See bug #4411 for more info.

111 # the library, as ldconfig should usually update it correctly
112 # to point to the latest version of the library present.

201 # 01_all_misc-fix.patch.bz2
202 # 02_sparc_another-fix.patch.bz2

971 # basically look for the first lseek command (we do the strings/grep because
972 # sometimes the function call is _llseek or something) and steal the 2nd
973 # parameter. here is an example:
974 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
975 # lseek
976 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
