dnl This is really sad and messy story

dnl Zsh needs three groups of functions:

dnl NIS (a.k.a. Yellow Pages)
|
|
|
|
|
dnl socket
|
|

dnl Depending on particlular OS (or even on particular OS version)
|
|
|
|
|
dnl these function may be found in -lc, -lnsl, -lresolv, -lsocket.
|
|
|
|
|
dnl Sometimes libraries depend on other (notorious -lnsl that is needed
|
|
|
|
|
dnl on SVR4-derived systems to get any network functionality at all)
|
|
|
|
|
dnl or must follow particular order (SINIX, that has two incompatible
|
|
|
|
|
dnl versions of gethostbyname() in -lsocket and -lresolv).
|

dnl So, this test tries to find minimal set of needed libraries;
