The impact is that the configure script will incorrectly decide that no compiler flag is needed to support C99 features. It should only be a problem on older compilers that don't support C99 by default. In my case, I noticed it with gcc version 4.2.1 (gccfss). > I just opened this new one.

The version of gcc you are using supports C11 features without requiring any flags. > This test used to work fine on the same system, which has not been > changed throughout the release cycle.

From the log it certainly appears that intmax_t is discovered correctly. I wonder if this is related: ./config.status: line 556: syntax error at line 562: `<<' unmatched - todd
