strtok used in mplsql.c
gmtime used in time.c
strerror used in stream.c, gzguts.h, mpl6.c, glprpr.c

gmtime_s does not seem to exist on Linux.
I guess this is yet another occasion for a configure check.

gmtime_s is included in the (optional) annex K of C11. However, the
parameters are reversed compared to the MSVC version and the standard
one returns struct tm * while

Not sure, but gmtime

Over glpk-4.61
src/env/time.c contains:
double glp_time(void)
{ struct timeval tv;
struct tm *tm;
int j;
double t;
gettimeofday(&tv, NULL);
tm = gmtime(&tv.tv_sec);
j = jday(tm->tm_mday, tm->tm_mon + 1, 1900 + tm->tm_year);
xassert(j >= 0);
t =
