[Simh] build of 37: undefined reference to `clock_getres'

[Eric Smith]

Sorry of this has already been addressed, I just joined, but:

I've enjoyed earlier versions of SIMH, but today I'm trying to build
the latest version 37 and I get this on Fedora Core 7:

[eric at gum 37]$ make USE_NETWORK=1
gcc -std=c99 -O2 -U__STRICT_ANSI__ -g -lm -D_GNU_SOURCE -I .
PDP1/pdp1_lp.c PDP1/pdp1_cpu.c PDP1/pdp1_stddev.c PDP1/pdp1_sys.c
PDP1/pdp1_dt.c PDP1/pdp1_drm.c PDP1/pdp1_clk.c PDP1/pdp1_dcs.c scp.c
sim_console.c sim_fio.c sim_timer.c sim_sock.c sim_tmxr.c sim_ether.c
sim_tape.c -I PDP1 -o BIN/pdp1
/tmp/ccnOESHT.o: In function `sim_os_ms_sleep_init':
/home/eric/simh/37/sim_timer.c:302: undefined reference to `clock_getres'
collect2: ld returned 1 exit status
make: *** [BIN/pdp1] Error 1

THANK YOU in advance!!
