htc.c and hts.c missing include of <time.h> for definition of time(...) #25
Description
Found as part of this effort:
https://fedoraproject.org/wiki/Toolchain/PortingToModernC
When compiling with strict C99 compliance we see that both htc.c and hts.c use time without the correct header being included
hts.c:433: implicit function declaration: time
There does seem to be some confusion on the web about whether sys/time.h should have this and it seems to vary on a per platform basis so simply including time.h might not be the right solution. So more elaborate configure magic might be required.
