The Jargon File (version 4.4.7, 29 Dec 2003):

delint
 /dee?lint/, v. obs.

    To modify code to remove problems detected when linting. Confusingly,
    this process is also referred to as linting code. This term is no longer in
    general use because ANSI C compilers typically issue compile-time warnings
    almost as detailed as lint warnings.

   /dee-lint/ To modify code to remove problems detected when
   linting.  Confusingly, this process is also referred to as
