Description

This is highleghted by newer gcc as in Fedora 26:

util/parser.c: In function Б─≤processБ─≥:
util/parser.c:199:28: error: comparison between pointer and zero character constant [-Werror=pointer-compare]
                 if ( *next == '\0' ) {
                            ^~
util/parser.c:199:22: note: did you mean to dereference the pointer?
                 if ( *next == '\0' ) {
                      ^
cc1: all warnings being treated as errors
make[4]: *** [autoMakefile:671: libcfsutil_a-parser.o] Error 1
make[4]: Leaving directory '/home/green/smt/git/lustre-release/libcfs/libcfs'

Apparently we really need to do double dereference on next.
