Again, it's been years and years. I agree.

The last time I tried the Compaq C compiler for Alpha-Linux it still worked, well, that is, the compiler worked, but the library header files are broken and haven't worked with glibc for a long time. So it is only useful as a free-standing compiler. In the past it also produced better code than gcc, but gcc is now so vastly improved w.r.t. optimisation and compliance to more recent standards, that I would be surprised if there is any real use for the Compaq compiler.
