[Help-glpk] Thred safety

[Heinrich Schuchardt]

Here is a list of functions that are not thread safe under POSIX 2008:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html#tag_15_09_01

Problematic coding includes:
strtok used in mplsql.c
gmtime used in time.c
strerror used in stream.c, gzguts.h, mpl6.c, glprpr.c

I wonder if dlsup.c is thread safe.

Best regards
