Include <pyconfig.h> ealier in Modules/expat/xmltok.c to define properly _POSIX_C_SOURCE. Python defines _POSIX_C_SOURCE as 200809L, whereas <features.h> (included indirectly by <string.h>) defines _POSIX_C_SOURCE as 199506L. (cherry picked from commit cf247359d5b7082044eea1fa94b5211a172b1ff6) Co-authored-by: Victor Stinner <vstinner@redhat.com>
