Yes : that is the case :
readelf -Ws /usr/local/vni/CTT3.0/lib/lib.linux/libimslcmath.so | grep 
__ctype_
  245: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND __ctype_b
  935: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND __ctype_tolower
 3561: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND __ctype_b
 4404: 00000000     0 NOTYPE  GLOBAL DEFAULT  UND __ctype_tolower
