4# All library objects contain sccsid strings by default; they may be
5# excluded as a space-saving measure.  To produce a library that does
6# not contain these strings, delete -DLIBC_SCCS and -DSYSLIBC_SCCS
7# from CPPFLAGS below.  To remove these strings from just the system call
8# stubs, remove just -DSYSLIBC_SCCS from CPPFLAGS.
9#
10# The NLS (message catalog) functions are always in libc.  To choose that
11# strerror(), perror(), strsignal(), psignal(), etc. actually call the NLS
12# functions, put -DNLS on the CPPFLAGS line below.
13#
14# The YP functions are always in libc. To choose that getpwent() and friends
15# actually call the YP functions, put -DYP on the CPPFLAGS line below.
16#
17# The Hesiod functions are always in libc. To choose that getpwent() and friends
18# actually call the Hesiod functions, put -DHESIOD on the CPPFLAGS line below.
