Thank you for a problem report. Verified just as described with 5.0.23-BK on Linux:

openxs@suse:~/dbs/5.0> bin/mysql -uroot test
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 5.0.23

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

Now it is shown, but reflects no value. See bug #37187 also.

note that it is shown in SHOW VARIABLES and INFORMATION_SCHEMA.GLOBAL_VARIABLES but it cannot be read as @@global.sql_slave_skip_counter, which is inconsistent

Pushed into 5.5.3-m3 (revid:alik@sun.com-20100306103849-hha31z2enhh7jwt3) (version source revid:vvaintroub@fedora12-20091225154921-x25a5pyw1pxiwobv) (merge vers: 5.5.99) (pib:16)

Noted in 5.5.3 changelog.

The value of sql_slave_skip_counter was empty when displayed by SHOW
VARIABLES or INFORMATION_SCHEMA.GLOBAL_VARIABLES.
