* #include <stdarg.h>
|
|
* #define MPFR_USE_VA_LIST
|
|
* #include <mpfr.h>
|
|
*
|
|
* where some_lib.h has "#include <mpfr.h>". So, the mpfr.h header file
|
|
* is included multiple times, a first time without <stdarg.h> before,
|
|
* and a second time with <stdarg.h> support. We need to make sure that
|
|
* the second inclusion is not a no-op due to some #include guard. This
|
|
* was fixed in r7320.
|
|
*
|
|
* Note: one needs to make sure that optimizations do not drop the call
|
|
* to mpfr_vfprintf.
