Details:
The macro expansion for wdt_enable() used for the ATtiny5/9/10/20/40 family
refers to the WDCE bit, which doesn't exist. Any invocation of wdt_enable()
will show this, I don't believe it merits an example file.
Watchdog change enable is accomplished by writing 0xD8 to the CCP register in
these devices. I'm not sufficiently familiar with inline assembly in GCC to
make a good job of fixing it myself - sorry!
The obvious workaround is to write the correct values directly to the relevant
registers.
