Copied from Linux kernel: commit 8f7c2c37319a81ef4c2bfdec67b1ccd5744d97e4 Date: Wed Apr 8 16:58:57 2009 +0800
This function converts static number to string in preprocessor. This is useful as it allows higher usage of puts() in favour of printf()
Fix commit message: this fonction is not limited to numbers.
