How to detect at compile time if I'm using gcc or icc? (I was quite puzzled to find out that icc defines <code>__GNUC__</code> -- and even <code>__GNUC_MINOR__</code> and <code>__GNUC_PATCHLEVEL__</code> ! why?)

We use <pre class="prettyprint"><code>#ifdef __INTEL_COMPILER </code></pre> to split <code>icc</code> off, assuming <code>gcc</code> as a default.

Detect ICC vs GCC at compile time

We use

#ifdef __INTEL_COMPILER

to split icc off, assuming gcc as a default.
