This is an approved src.alt for 400.perlbench in CPU2006 v1.0 and v1.0.1.
It will allow compilers that do not define _MSC_VER to get typedefs for POSIX
ID types that are not provided by the platform header files.

To apply the src.alt, unpack the tar file in the top level of the CPU2006
directory.  The following sequence of commands should accomplish this:

$ /bin/sh
$ cd <cpu2006 dir>
$ . ./shrc
$ go top
$ specbzip2 -dc <src.alt tarball> | spectar -xvf -

Please replace the items in angle brackets ( <> ) as appropriate.

To have the src.alt applied during compilation, please add the following
stanza to your config file:

# Get POSIX ID typedefs
400.perlbench:
srcalt=need_posix_ids
CPORTABILITY=-DSPEC_CPU_NEED_POSIX_IDS

Because this src.alt adds a new flag, in order to avoid having
"-DSPEC_CPU_NEED_POSIX_IDS" marked as an "unknown" flag, it is necessary to
update the flags files in your distribution.  You can do this by running

$ runspec --newflags

For more information on this option, see

  http://www.spec.org/cpu2006/Docs/runspec.html#newflags

Information on setting HTTP proxies is at

  http://www.spec.org/cpu2006/Docs/runspec.html#http_proxy

This src.alt makes one performance neutral portability-related change to
400.perlbench.

On Windows, the Microsoft header files do not have definitions for the 
POSIX identifiers gid_t, uid_t, and mode_t.  Because of this, 400.perlbench
adds these identifiers only if "_MSC_VER" is defined.  

This src.alt adds support for other compilers that may also need these 
identifiers.

Please address any questions about this src.alt to cpu2006support@spec.org.
