Hello,
Attempting to build libiberty on LynxOS-178 fails trying to compile
mkstemps.c with the following error:
mkstemps.c:84:18: error: storage size of 'tv' isn't known
struct timeval tv;
^
This file would normally include <sys/time.h> to get the type's
definition, but unfortunately LynxOS-178 does not want us to use
<sys/time.h>, only <time.h>. The configure script correctly finds
this out and generates a config.h file where HAVE_SYS_TIME_H is
undefined:
/* Define to 1 if you have the <sys/time.h> header file. */
/* #undef HAVE_SYS_TIME_H */
This patch fixes the build issue by falling back on including <time.h>
if <sys/time.h> could not be included (and provided that HAVE_TIME_H
is defined, of course).
libiberty/ChangeLog:
* mkstemps.c: #include <time.h> if HAVE_TIME_H is defined
but not HAVE_SYS_TIME_H.
OK to commit?
Thank you,

Joel
