#### Tru64 Pragmas

For compatibility with the Compaq C compiler, the following pragma is supported.

`extern_prefix` string``

  This pragma renames all subsequent function and variable declarations such that string is prepended to the name. This effect may be terminated by using another `extern_prefix` pragma with the empty string.

  This pragma is similar in intent to to the asm labels extension (see Asm Labels) in that the system programmer wants to change the assembly-level ABI without changing the source-level API. The preprocessor defines `__PRAGMA_EXTERN_PREFIX` if the pragma is available.
