--- Comment #8 from Carsten Schlote <[email protected]> --- For everyone ending up here, due to this bug: Using 'gcc -D_WCHAR_H -E -o output.i input.{c|h}' fixed the problem for me, as it prevents 'wchar.h' to be included, which contained the problematic special keywords of GCC. Of course, this will only work, if you do not need wchar features in your imported C sources. --
