| 13 | * | |
| 14 | * <stdio.h> provides fgetpos64, fopen64 if __USE_FILE_OFFSET64 is defined. | |
| 15 | * It then checks whether a gcc-specific __REDIRECT macro is available | |
| 16 | * (defined in <sys/cdefs.h>, depending on __GNUC__ begin available). | |
| 17 | * If it is not available, it does a preprocessor #define. | |
| 18 | * Which <cstdio> undefines, with this comment: | |
| 19 | * "// Get rid of those macros defined in <stdio.h> in lieu of real functions.". | |
| 20 | * When it does a namespace redirection ("namespace std { using ::fgetpos; }") it goes blam, as | |
| 21 | * fgetpos64 is available, while fgetpos is not. | |
