Public bug reported:
So crypt(3) from the binary package manpages-dev tells me I should have
crypt(), usable with -lcrypt.
As I sometimes needs to compute such a crappy hash (I can't even
remember when the last time was, or why, but that had to do with legacy
code), I wrote this small utility:
https://github.com/pcarrier/stuff/commit/f3de13682f28354397dc1b7caef5c1dd13fdfc36
It compiles completely fine under Squeeze using "gcc -lcrypt crypt.c".
For some reason I'm not so lucky with precise.
