Thank you for your bug report.

To fix this annoying error please insert a line in file src/glplib05
as follows:

81    #elif GLP_TM_SPEC == 1
82
83    /* GNU/Linux version */
84
++    #include <stddef.h>
85    #include <sys/time.h>
86    #include "glplib.h"
87
88    double lib_get_time(void)

and then run make as usual.
