If your functions define completely new but rarely used functionality,
you should probably consider packaging it as a separate library.
+License
+-------
+
+GNULib contain code both under GPL and LGPL. Because several packages
+that use GNULib are GPL, the files state they are licensed under GPL.
+However, to support LGPL projects as well, you may use some of the
+files under LGPL. The "License:" information in the files under
+modules/ clarify the real license that apply to source.
+
+Keep in mind that if you submit patches to files in GNULib, you should
+license them under a compatible license. Which means that sometimes
+the contribution will have to be LGPL, if the original file is
+available under LGPL via a "License: LGPL" information in the
+projects' modules/ file.

How to add a new module
-----------------------
Even if the include files conform to C89, the library itself may not.
For example, SunOS 4's (free (NULL)) can dump core, so GNULib code
must avoid freeing a null pointer, even though C89 allows it.
+You can work around some of these problems by requiring the relevant
+modules, e.g., the GNULib 'free' module supplies a conforming 'free'.
The GNU coding standards allow one departure from strict C99: GNULib
code can assume that standard internal types like size_t are no wider
as well. GNULib code makes the following additional assumptions:
* Signed integer arithmetic is two's complement, without runtime
- overflow checking.
+ overflow checking. This is the traditional behavior, and is
+ supported by C99 implementations that conform to ISO/IEC 10967-1
+ (LIA-1) and that define signed integer types as being modulo.
* There are no "holes" in integer values: all the bits of an integer
contribute to its value in the usual way.
