Yes, but if in the standard headers something odd is done with the mktime 
symbol and mktime is redefined then it could end up with a build error. It 
might be better than a runtime error (but not always). 

In fact I throw this issue because I have a report that on a redhat 
entreprise linux 3 with C++, gnulib wants to use its mktime, but in the
C++ headers mktime is undefined and then there is a build error. I'll
try to gather more information, maybe changing mktime to rpl_mktime
in mktime.c doesn't help. 

I had a look at the other source files, and in many cases the function is
called with rpl_ appended (rpl_putenv, rpl_mkstemp, rpl_mkdir....).
What is the rule for add rpl_ to the function names or not?
