- Authentication-results: sourceware.org; auth=none
MPFR_RNDx was introduced in MPFR 3.0.0. Since the minimal version that
gcc checks for is 2.4.0, this leads to a build failure.
The fix is straightforward.
Tested on x86_64-pc-linux-gnu. Committed to trunk as obvious.
* gimple-ssa-sprintf.c (format_floating): Change MPFR_RNDx to
GMP_RNDx for compatibility.
