vasnprintf.c shadowing warnings cause "make distcheck" failure

[Jim Meyering]

vasnprintf.c uses variables named exp and remainder, and they shadow
math functions.  This poses a problem for me, since coreutils' "make
distcheck" requires a clean build with -Werror -Wshadow.

Bruno, any objection to this change?

Subject: [PATCH] Rename locals to avoid shadowing warnings.

* lib/vasnprintf.c (exp): #define to vasnprintf_exp.
(remainder): #define to vasnprintf_remainder.
