How do I fix Eclipse CDT Error "Function 'isdigit' could not be resolved" with Android NDK?

I am using Eclipse Indigo with an Android/NDK mixed project. I've added C++ nature and almost everything is working. Automatic builds work; that is, when I edit a file ndk-build is invoked and completes successfully - no build errors. Mouseover code assist works (the little window pops up with information about the function). If I place the cursor on an include line and press F3, a relevant header file open (not the one I would expect based on my configuration, but a relevant one - maybe a clue?). If I select the following line in my .cpp file, it opens $NDKROOT/platform/android-3/arch-arm/usr/include/ctype.h: ``` #include <ctype.h> ``` (isdigit is defined in this file) However, Eclipse insists that isdigit is not defined. I have read many posts suggesting that either the static analyzer or the indexer is to blame, but I've tried many of the suggested solutions to no avail. If I add a line like the following, the error goes away and mouseover code assist for the function works: ``` extern int isdigit(int); ``` Again, this is not a linker error or a compiler error - ndk-build completes with no errors. This is something inside eclipse. Thanks for taking a look! Edit: I now believe this to be a Code Analysis problem. A better solution is to edit the Code Analysis options to make "Function could not be resolved" be a warning instead of an error. That way you can see the warnings in Problems view, but continue to work. If the function is REALLY missing, the compiler will tell you! I also have a new theory, that the problem is with the Code Analyzer following symlinks, because all of the "missing" functions are in symlinked include files. Would love any input on this theory.
