[Bug c/26386] strdup "implicit declaration" warning when using -ansi

Subject: Re:  strdup "implicit declaration" warning when using -ansi

I see.  Sorry for a needless bug report.  But thank you for your
helpful responses.  I expect
I really will need to use -ansi (--> STRICT_ANSI), so I'll have to do
without strdup.
