 This is due to the "/* Check for concatenated .gz files: */"
 block of code in cread.c around line 290.

 it's a gzipped file:

 $ file -sz /mnt/netbsd                                       
 /mnt/netbsd: ELF 64-bit LSB executable, x86-64, version 1 (SYSV) (gzip compressed data, from Unix, max compression)

 In my source tree, this is line 388.
 What fix do you propose?

 I retried with an iso built by releng autobuilder from
 2010-03-22.

 Booting a kernel still fails the same way:

 I retried with an iso built by releng autobuilder from
 2010-03-24 which contains the commit.

 NetBSD boots again.
 This PR can be considered fixed.
