Re: [Tinycc-devel] Bug that TinyCC Analyses Strings inside #if 0 blocks

[Domingo Alvarez Duarte]

Hello Ziyao !

Although gcc compiles a file containing your example with warnings, I'm 
not sure it's worth try to do the same in TiinyCC the preprocessor 
probably uses TOKENS from the lexer to decide to skip till the end of 
the initial "#if 0" and '"' is not a valid token the error probably come 
from the lexer that found a non terminated string.

Cheers !
