Thanks.  I'm not sure why you're seeing this because time.h should be
included by makeint.h.

When providing patches for errors like this, it would be very helpful
if you could also include the compiler error you got (cut and paste is
best), and also if you could send me your src/config.h file so I can
take a look at it that would be helpful.

Thanks!

   Suppress extern inline with HP-UX cc, as it appears to be broken; see
   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.

   Suppress extern inline with Sun C in standards-conformance mode, as it
   mishandles inline functions that call each other.  E.g., for 'inline void f
   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
   'reference to static identifier "f" in extern inline function'.
   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.

   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
   on configurations that mistakenly use 'static inline' to implement
   functions or macros in standard C headers like <ctype.h>.  For example,
   if isdigit is mistakenly implemented via a static inline function,
   a program containing an extern inline function that calls isdigit
   may not work since the C standard prohibits extern inline functions
   from calling static functions (ISO C 99 section 6.7.4.(3).
   This bug is known to occur on:

     OS X 10.8 and earlier; see:
     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html

     DragonFly; see
     http://muscles.dragonflybsd.org/bulk/bleeding-edge-potential/latest-per-pkg/ah-tty-0.3.12.log

     FreeBSD; see:
     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html

   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
   Assume DragonFly and FreeBSD will be similar.

   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
   inline semantics, unless -fgnu89-inline is used.  It defines a macro
   __GNUC_STDC_INLINE__ to indicate this situation or a macro
   __GNUC_GNU_INLINE__ to indicate the opposite situation.
   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
   semantics but warns, unless -fgnu89-inline is used:

Re: gmake-4.2.90 patch

This is the reason for your problem.  On my system, this is defined.

What version of GNU/Linux are you using?

What this undefined value means is that as far as autoconf is
concerned, it's not valid to include both <sys/time.h> and <time.h> at
the same time on the same system.  In this situation, if
HAVE_SYS_TIME_H is defined (which it is for you) then <sys/time.h> will
be included but not <time.h>.

The fact that you can add an include of <time.h> into file.c and have
it not fail shows that in fact, it IS OK to have both these headers
included at the same time, which means that the configure check got it
wrong.

Can you email me (privately please, not to the entire list) your
config.log file, or go through it to find the errors that were
generated when configure attempted to determine whether both these
headers can be included?

Thanks!
