Why does Eclipse CDT say: 'syntax error', but compilation no problem

Question

I am working in existing C code which has a couple of lines with statements similar to this one:

struct collect_conn *tc = (struct collect_conn *) 
     ((char *

Sometimes, although the code compiles with no error, eclipse CDT's real-time code analyzer shows some errors in C/C++ files (eg. 'Function xxx could not be resolved). This is because eclipse CDT uses its own preprocessor/parser for analyzing the code and building the indexes instead of the MinGW's one (or any other GNU compiler). In order to fix this globally for all eclipse projects in the workspace, follow these steps: (In order to fix this only for a specific project, follow steps 1, 2 and 4 in menu 'Project->Preferences')

1-In menu 'Window->Preferences->C/C++->Language Mappings', add the correct mappings as shown in below: (eg. for content types: C++ Source/Header File, use GNU C++ language and so on)

2-In menu 'Window->Preferences->C/C++->Indexer', set full indexing by checking all checkboxes (but not 'Skip' ones) as shown in below:

3-In each project's specific properties, menu 'Project->Properties->C/C++ general->Indexer', Uncheck 'Enable project specific settings' as shown in below:

4-Rebuild the indexing, menu 'Project->C/C++ Index->Rebuild'.
