[PATCH] strptime.3: add #define to example to avoid implicit declaration of strptime

[PATCH] strptime.3: add #define to example to avoid implicit declaration of strptime

[Carlo Marcelo Arenas Belon]

The example doesn't follow the guidelines given in the description and will
result in the following warning if compiled :

  In function 'main':
  13: warning: implicit declaration of function 'strptime'

Hi Carlo,

Thanks for your report. _GNU_SOURCE will do the job, but as documented
in the man page, _XOPEN_SOURCE is the precise macro required.  So I
added that to the example program.  The change will be in
man-pages-2.76.
Cheers,

Michael
