    Problem Summary TSD4C.00211 This request claims that an implementation need not support execution of executables c89 produces for all programming environments the implementation claims support for.
    Problem Text

    These tests compile a program that tests the int, long, pointer and off_t size
    and return those values to the main testcase. The test programs is compiled
    using the values of the XBS5* macros. However, the XBS5* macro only determine
    compilation environments not execution environments. From getconf on page 380,

    "OPTIONS ....
    getconf -v _XBS5_ILP32_OFF32 ...
    will determine values for configuration variables corresponding
    to the XBS5_ILP32_OFF32 compilation environment specified in c89,
    EXTENDED DESCRIPTION."

    While it is possible to compile _XBS5_LP64_OFF64 and _XBS5_LP64_OFF64
    programs on our _XBS5_ILP32_OFF32 systems, they cannot be executed on
    these systems.

    Review Response
    We recommend this request be refused.

    Although it could be stated more clearly we believe the spec authors
    intend implementations only state they support "Programming Environments"
    that produce programs which may be executed on the implementation. It
    is not enough that the implementation merely generate a binary which
    it claims can be run elsewhere.

    Our basis for this belief lies in the fact that c89 must be capable of
    compiling "executable files" for all programming environments the
    implementation supports. The XBD definition of executable file is
    as follows

    A regular file acceptable as a new process image file by the
    equivalent of the exec family of functions, ...

    Review Conclusion
    The Base WG agrees that the waiver should be granted.

    The description of _XBS5_ILP32_OFF32 in XCU5's description of
    getconf relates to the unistd.h definition from XSH5 which states
    that:

    "Implementation provides a C-language compilation
    environment with 32-bit int, long, pointer and off_t types.i"

    Note that this describes the "compilation environment".
    It does not describe the execution environment.
    The descriptions of _XBS5_ILP32_OFFBIG,
    _XBS5_LP64_OFFBIG, and _XBS5_LP64_OFF64 are similar.

    The Base WG recommends that in a future issue/revision of the
    specification that some way be added to
    determine what execution environments are supported as well as what
    compilation environments are supported.
    It is recommend that consideration be given to the
    addition of the following symbols to be added to <unistd.h> and made
    available to applications through getconf and sysconf():

    _XBS_ILP32_OFF32_EXEC
    Implementation provides an execution environment to run
    applications built in the _XBS_ILP32_OFF32 C-language
    compilation environment.

    _XBS_ILP32_OFFBIG_EXEC
    Implementation provides an execution environment to run
    applications built in the _XBS_ILP32_OFFBIG C-language
    compilation environment.


    _XBS_LP64_OFFBIG_EXEC
    Implementation provides an execution environment to run
    applications built in the _XBS_LP64_OFFBIG C-language
    compilation environment.

    _XBS_LP64_OFF64_EXEC
    Implementation provides an execution environment to run
    applications built in the _XBS_LP64_OFF64 C-language
    compilation environment.

    Until this is done, the Base WG recommends addition of a question to
    the CSQ to ask which execution environments are
    supported on the System Under Test. Lastly the Base WG recommends that
    a future revision address how to allow an application to
    determine which compilation and execution environments are the default.
