14.14 Library functions
Describes implementation-defined aspects of the ARM C compiler and C library relating to library functions, as required by the ISO C standard.
The ISO C library variants are listed in ARM C and C++ Libraries and Floating-Point Support User Guide.
The precise nature of each C library is unique to the particular
implementation. The generic ARM C library has, or supports, the

If a program redefines a reserved external identifier
