# This is a replacement for bsd.lib.mk for the libc project to get it
# doing the Right Thing in XBS, which is substantially different than
# the BSD build system.
#
# The main problems arise when libc.a isn't meant to be static, but
# libc_static.a is.  We also build a debug version of the library
# in addition to shared, static, and profile.  Also, we build all 
# versions of libc with debugging enabled, unstripped.  The BSD style
# is to strip every object file after it is built but here, libc.a
# will get merged into the larger libSystem.dylib, which will eventually
# be stripped.  We also don't build a libc.dylib, since it will be
# munged into libSystem.dylib.
#
# And another difference, B&I wishes to build the 4 incarnations of Libc
# in parallel on different machines.  To do this, we must look at the
# RC_ProjectName variable (which B&I sets) to determine which of the 4
# versions of Libc we will be building.  Remember that the installhdrs
# pass should only be invoked on one of the 4 versions, and man pages
# should only be installed once as well.  Both of these get done when
# we're invoked as "Libc".
