[LLVMdev] Header File Not Found?

[Eric Mader]

I'm having a strange problem compiling with VS 2013. It's not finding a 
header file that's there in one of the header file search dirs.

Here's the compile command (with the names changed to protect the 
innocent ;-)

1>  C:\Program Files (x86)\LLVM\msbuild-bin\CL.exe /c 
/IC:\[top-level-dir]\[source-dir]\ 
/IC:\[top-level-dir]\[source-dir]\[sub-dir-1] 
/IC:\[top-level-dir]\[source-dir]\[sub-dir-2] 
/IC:\[top-level-dir]\[dest-dir]\[dest-sub-dir]\include 
/IC:\[SDK-dir]\[SDK-source-dir]\[SDK-sub-dir]\include

/FIC:\[top-level-dir]\[source-dir]\\[prefix-header].h 
/errorReport:prompt -m64 -fmsc-version=1800 -ferror-limit=1000 -m64 
-fmsc-version=1800 [source-file].cpp

And here's the error:

1>  In file included from [source-file].cpp:9:
1>  In file included from 
C:\[top-level-dir]\[source-dir]/[source-file].h:12:
1>C:\[top-level-dir]\[source-dir]/[another-header-file].h(14,10): fatal 
error : '[UPPER-CASE-NAME].h' file not found
1>  #include "[UPPER-CASE-NAME].h"

[UPPER-CASE-NAME].h is in C:\[top-level-dir]\[source-dir]\[sub-dir-1]\

(I wonder a bit about the forward slash in the third error line, but I 
assume it's just how the error message is formatted)

Does anyone have any idea what 's going on here. The header file is 
clearly in one of the directories on the list of search directories, and 
yet the compiler is saying it can't find it.
