# Tests for special targets like .BEGIN or .SUFFIXES in dependency
# declarations.
# TODO: Implementation
# Just in case anyone tries to compile several special targets in a single
# dependency line: That doesn't work, and make immediately rejects it.
.SUFFIXES .PHONY: .c.o
# The following lines demonstrate how 'targets' is set and reset during
# parsing of dependencies. To see it in action, set breakpoints in:
#
# ParseDoDependency at the beginning
# FinishDependencyGroup at "targets = NULL"
# Parse_File at "Lst_Free(targets)"
# Parse_File at "targets = Lst_New()"
# ParseLine_ShellCommand at "targets == NULL"
#
# Keywords:
# parse.c:targets
target1 target2: sources # targets := [target1, target2]
: command1 # targets == [target1, target2]
: command2 # targets == [target1, target2]
VAR=value # targets := NULL
: command3 # parse error, since targets == NULL
