stdio.h and the files it includes from Embarcadero C++Builder none

Description Josh Kelley CLA 2011-06-28 21:40:33 EDT 
Build Identifier: 20110615-0604

I'm unable to get Eclipse's indexer to recognize functions and types (like FILE) in stdio.h.

Some other C library functions work, and some don't.

I'm using Eclipse CDT to edit Embarcadero (formerly CodeGear, formerly Borland) C++Builder projects.  It has a few vendor extensions to C++, but I can't see where those would affect C runtime libraries.  

I do not believe that this problem is new to CDT 8.0, but Codan's "could not be resolved" error messages make it much more obvious.

If I press F3 in "#include <stdio.h>", Eclipse opens stdio.h as expected, so it is able to resolve the #include.

Reproducible: Always

Steps to Reproduce:
1. Open a C++Builder project in Eclipse CDT.
2. Open a source file that calls fopen or sprintf.
3. Note all the complaints from Codan.

Maybe some headers are included multiple times? (Bug 197989)

I think that this issue is unrelated.  If I include only stdio.h, I get the same symptoms.

I mean inside stdio.h. Can you see files included multiple times in stdio.h or files that it includes?

I checked, and stdio.h has no duplicate includes.

Please attach the version of stdio.h you are using.

stdio.h and the files it includes are attached.

Hmm, I don't see any problems using these header files. I created a project with the headers added 'test.c' which includes 'stdio.h' and uses FILE. Does it work for you if you do the same?
Please share a code snippet where 'FILE' cannot be resolved and create a parser-log for the file containing the snippet (Context menu of file in project explorer - Index - Create Parser Log).
