AIX 4.2
System: AIX melville 2 4 000010504900

login.krb5 reads /etc/environment with no-override setenv(),

Machine: RS/6000
>Description:
In appl/bsd/login.c, setenv("PATH", LPATH, 1) overwrites a value for
PATH from /etc/environment, read a few lines earlier.
>How-To-Repeat:
Login on AIX with local PATH value in /etc/environment
>Fix:
Reduce that to setenv("PATH", LPATH, 0), i.e., supply as default but
don't overwrite.
