Re: [Tinycc-devel] Dollar Sign in Identifiers Extension

[Daniel Holden]

Hi,

I like the idea of using std=c99 to disable. I believe this is how gcc/clang handle it. But ultimately I don't mind too much. gcc/clang use the switch "-fdollars-in-identifiers" (I've attached a modified patch) although in almost all cases it is enabled by default so they also provide "-fno-dollars-in-identifiers".

https://gcc.gnu.org/onlinedocs/gcc-3.0.4/gcc_3.html

I'm mainly interested in this change because I'm working on a new version of my library Cello: http://libcello.org/ which uses `$` and several variations of as macros. There is also RayLanguage which also uses it as a macro for a kind of ObjC style message passing: https://github.com/kojiba/RayLanguage . But I can also put together some test cases using it in the various ways (variable, function, macro, define, etc) so make sure it is completely covered.

Thanks,

Dan

Looks good at quick look. I'm not sure about the switch, we already accept 
some gnu extension without any switch for that. Or maybe introduce a more 
general switch for all C extensions. You could enable it by default en disable 
it if std=c99 for instance?

Best regards,

Thomas
