           Summary: Thread Creation Example Utilizes Incorrect Cast
           Product: eCos
           Version: unknown
          Platform: mxlads_a (Motorola M9328MXLADS/A board)
               URL: http://ecos.sourceware.org/docs-latest/ref/kernel-
                    thread-create.html
        OS/Version: ARM
            Status: UNCONFIRMED
          Severity: normal
          Priority: normal
         Component: Reference Guide
        AssignedTo: jifl@ecoscentric.com
        ReportedBy: Tony.Garland@fluke.com

The example code under "Thread Entry Points and C++" does not compile on gcc
because it shows a static_cast where a reinterpret_cast is required.

This snippet:

cyg_thread_create( ...,
    &fred::static_thread_aux,
    static_cast<cyg_addrword_t>(&instance),
    ...);

Should be:

cyg_thread_create( ...,
    &fred::static_thread_aux,
    reinterpret_cast<cyg_addrword_t>(&instance),
    ...);

static_cast cannot be used to change a pointer (&instance) into a non-pointer
(cyg_addrword_t which is unsigned int on our platform).
