12375,Patch fixing use of boost::icl w/ MSVC CL.exe /P,anonymous,Joachim Faulhaber,"This patch makes it possible to use this header in programs built using
the FASTbuild (http://fastbuild.org) and more precisely its caching
feature.

Considering the following code:

clmacro.cpp:
{{{
int main(void)
{
#define funny_type(x) x
funny_type(int)const a = 2; // cl.exe -P clmacro.cpp -> `intconst a`
}
}}}

On MSVC (Visual Studio 2013)
Microsoft (R) C/C++ Optimizing Compiler Version 18.00.40629 for x86
Copyright (C) Microsoft Corporation.  All rights reserved.

This compiles correctly by default with `CL.exe`

{{{
Cl.exe clmacro.cpp
}}}

However when using the `/P` compilation flag to obtain the pre-processed
source, then trying to compile the resulting file this will fail because
const gets stitched to the other symbol before compilation.

See:

{{{
cl.exe -P -Ficlmacro.i.cpp clmacro.cpp && cl.exe clmacro.i.cpp
