[Tinycc-devel] RE : CFront for TinyCC? (Was: Re: Re: global 64-bit variables initialization)

[Christian JULLIEN]

Having the rights to use CFRONT 3.0.3 is far from clear.
For common usages, CFRONT 3.0.3 is close to 'modern C++' and it's easy to download the latest source code from http://www.softwarepreservation.org/projects/c_plus_plus.
With probably little efforts, we could have this front end working well with tcc.

If put efforts to have a tcc backend for CFRONT, we should only supply Makefile and .patch for AT&T source file with a similar notice:
