lint does not understand C++-style comments.  gcc does understand them,
and they are part of the new C99 standard.

Lint(1) says "lint - a C program verifier", so it is not clear it should 
unterstand C++ syntax. While // is part of ISO 9899:1999 (C99) our lint  
does not support any new syntax introduced by C99, like struct literals, 
flexible arrays and others. So instead of supporting just one feature of 
C99, the // comments, I think it is better to have lint actually reject 
// as it is clearly a syntax error for C89 and many compilers do not            understand it. Lint is also a portability checker, intended to pick             fluff off of C code and // is non-portable fluff. BTW, gcc does NOT 
understand // in -ansi -pedantic mode. 

Of course we would be pleased if you provided a patch to make lint 
(optionally) fully C99 aware and this would have a near 100% chance of 
making it into the tree.
