Hi Claudio,

This suggestion would not help fixing the problem, because the problem was
that malloc and/or realloc were not declared, according to the compiler error
message.

1. Yes, some gnulib modules are used in C++ mode, when people compile with
   CC=g++. (This is used in GNU clisp, for example.)
2. setenv.c is taken from glibc, and glibc's setenv.c contains this cast as
   well.
