Bug#659510: tokyocabinet: FTBFS on hurd, do to missing msync syscall

[Tobias Frost]

Package: tokyocabinet
Severity: important

Dear Maintainer,

on hurd tokyocabinet fails because hurd does not have the msync syscall.

The log can be found here:
https://buildd.debian.org/status/fetch.php?pkg=tokyocabinet&arch=hurd-i386&ver=1.4.37-6.1&stamp=1304440721

The attached patch will conditionally compile not to use msync on hurd.

I intend to ask for a NMU because of this issue.

Best regards
coldtobi
