/* Seen in the wild:
* Self-extracting PRO2K3XP_32.exe contains 19078464 byte zip archive,
* where CDE was nearly 48 kbytes before EOF.
* (Surprisingly, it also apparently has *another* CDE structure
* closer to the end, with bogus cdf_offset).
* To make extraction work, bumped PEEK_FROM_END from 16k to 64k.
