Patch 7.2.044
Problem:    Crash because of STRCPY() being over protective of the destination
	    size. (Dominique Pelle)
Solution:   Add -D_FORTIFY_SOURCE=1 to CFLAGS.  Use an intermediate variable
	    for the pointer to avoid a warning.
Files:	    src/auto/configure, src/configure.in, src/eval.c
