6359	Intel Composer XE 2011 (12.0) fails to build Boost.Regex with ICU support	Brian Bassett <bbassett@…>	John Maddock	"=== Environment ===

* Intel C++ Composer XE 2011 Update 8 for Windows (version 2011.8.278/12.1.2.278)
* Boost 1.48.0
* ICU 4.8.1.1 (using binaries downloaded from http://download.icu-project.org/files/icu4c/4.8.1.1/icu4c-4_8_1_1-Win32-msvc10.zip)

=== Reproduce Steps ===

1. Apply the attached patch (icubld.patch) in order to correctly have Boost.Build use the correct names for the ICU DLLs with the Intel toolset.

2. Unpack the Win32 ICU binary distribution to a temporary directory (i.e., `C:\tmp\icu`).

3. Start a command prompt with the Intel Composer XE 2011 environment (i.e., Start Menu -> All Programs -> Intel Parallel Studio XE 2011 -> Command Prompt -> Parallel Studio XE with Intel Compiler XE v12.1 Update 2 -> IA-32 Visual Studio 2010 mode)

4. Change directory into the Boost source tree and run:

{{{
b2 --build-type=complete toolset=intel-12.0 address-model=32 -sICU_PATH=C:\tmp\icu stage
}}}

5. Observe that building `libs/regex/src/icu.cpp` fails with the following error:

Note that I've ommitted the remarks and warnings output by icl for clarity.

=== Additional Comments ===

Note that I've had no problems building this file on Linux using the same version of Intel's Linux compiler (2011.8.273), nor with earlier versions (11.1) of Intel's Windows compiler.  This compiler (intel-win-12.0) is the only one I can trigger this compilation error.  As such, I suspect this is actually a compiler bug with Intel.  If it turns out to be such, please let me know and I can follow up with Intel directly.
