Re: (re)compiling debian packages with ccc



Since everyone immediately gravitated to legal issues, I repost the
technical piece.  ;)

I have joined the libtool mailing list and will add ccc as a recognized
compiler to libtool.  Are there other issues with 
    apt-get source ... dpkg-buildpackage
that anyone knows of?  (aside from ccc failing to compile some files)

Since people claim gcc3 is so good, I will have to run some
benchmarks...
