Short answer: Compiler specific.
Long answer: According to K&R Second Edition, a variable name may be of any length; however, only the first 31 characters are significant. Compilers are free to extend this beyond 31, and may make any number of characters significant.

>only the first 31 characters are significant
For local variables, variables and functions with external scope are only guaranteed to be signifigant to the first 6 characters.

My best code is written with the delete key.
Though I would recommend not to use very long names. They make code not very readable.
