New Could autoconf help?
I've seen lot of programs do build-type checks in autoconf.

Wade.

Microsoft are clearly boiling the frogs.

New We have our own build system; autoconf not a part of it

New Autoconf could still be useful
The way it works is that it runs a bunch of tests to figure out what the environment is. Even if you have your own system, you could download autoconf and steal the tricks they are using.

New Autoconf does so at runtime.
ie. through uname, etc.

Which isn't particularly useful during compile time. :-)

New Are we talking about "configure" script?
As used by scores of Open Source apps? It works _before_ compile time.

We have only 2 things to worry about: That
things will never get back to normal, and that they already have.

New You misunderstand me.
The techniques that configure/autoconf use are runtime techniques, and hence useless to my goal of doing the configuration at compile time. :-)

Basically, I ended up using stuff like:

\n#if defined(MSC_VER)\n// windows stuff\n#elif defined(linux) || defined(__linux__)\n// linux stuff\n#elif defined(sun) || defined(__sun__)\n// solaris stuff\n#else\n#error Unknown or unsupported OS\n#endif\n

New One man's compile time...
...is another man's run time. How about having the make file run a configuration procedure that generates a header file with the constants in it. Something with pipes or grep or awk or.... :-)

New I already do that; I don't want to. :-)
Or at least, something similar. I want the entire detection to happen in the source code, not as the result of something that runs before the compile.

New So what you're really wanting is...
...to know if the compiler itself is autodetecting the environment and whether that detection is available in the conditional compilation?

Here's what I came up with, which seems to work fine:
