Found.  Optimization triggers it.

$ cat atest.c
#include <stdio.h>
#include <ctype.h>

int main(int argc, char **argv)
{
        printf("%c\n", toupper('a'));
        return 0;
}

Success:
$ apgcc atest.c -o atest
$

Fail:
$ apgcc -O3 atest.c -o atest
/tmp/cc6UgLDq.o: In function `main':
atest.c:(.text+0x7): undefined reference to `__ctype_toupper@GLIBC_2.0'
collect2: ld returned 1 exit status

Any ideas other than turning off optimization?
