I am using Visual Studio 2014 CTP (VC14) and cannot get Firefox to pass through configure.

Create a foo.c file with the following content:

    #include <stdio.h>

Then run the following command:

    cl -c -nologo -Fonul -showIncludes foo.c

What is the output?

I am using dummy-hello.c and this is the result.

$ cl -c -nologo -Fonul -showIncludes dummy-hello.c
dummy-hello.c
Note: including file: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INC
LUDE\stdio.h
Note: including file:  C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\IN
CLUDE\corecrt.h
Note: including file:   C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\I
NCLUDE\vcruntime.h

CLUDE\corecrt_wstdio.h
Note: including file:   C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\I
NCLUDE\corecrt_stdio_config.h

I think the regex matches with these 2 lines:

Note: including file: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INC
LUDE\stdio.h
Note: including file:  C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\IN
CLUDE\corecrt_wstdio.h

so $_CL_STDIO_PATH becomes 

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE\stdio.h C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE\corecrt_wstdio.h

and the test statement always returns true.
