+[src/mpfr-impl.h] Removed the detection of possible inconsistencies
+under Unix because the tests could yield spurious errors with Cygwin
+or other similar implementations. Moreover, such tests were used for
+debugging purpose or to detect potential problems in the environment,
+thus were not really useful for the end user. They were initially
+added in the win-thread-safe-dll branch (r9682, following a problem
+found in r9680). One alternative for checking by the MPFR developers
+would be to output the status of some internal macros in tversion.
