Hm.. Perhaps some macros are messing things up? How is fgetpos() declared?

As an experiment, you can try declaring fgetpos yourself, before
including the failing headers and see whether your declaration will
conflict with something inside system headers, to give you more clues
for a workaround.

Here is a minimal test case that can be inserted and modified as needed:

    #include <stdio.h>
    // our own declaration; should not be needed and may conflict
    int fgetpos(FILE *stream, fpos_t *pos);

    namespace TestSpace {
       // should work unless fgetpos is a macro
        using ::fgetpos;
    }

HTH,

Alex.
