The CDT FAQ says

any macro's necessary to read stdio.h are set (often a missing macro will
cause a system header to encounter a #error in the header file -- for
example on windows using cygwin, the defining the symbol __i386__ will
allow stdio.h to be understood)

unfortunately it is not always aceptable to add a #define to the source
code
many IDEs and editors solve this problem by allow the user to specify a
set of predefined macros, but I failed to locate such a facility in CDT

in othercases compilers predefine macro to indicate which compiler and
version is in play, in my case such a solution would also be acceptable
but I was not able to locate the name of such a macro
if it exists I could add some thing like the following to may files:

#ifdef __ECLIPSE_CDT_COMPILER
#define MY_MACRO
#endif

This facility exists in the CDT.

-- Open the project properties window.

-- Select C/C++ Include Paths & Symbols.

-- Click on the button labeled Add Preprocessor Symbol.

-- Type in the symbol you want to define, followed optionally by '=' and
the value you want for that symbol.
