21 ## We used to define this. However, we don't because vendor makes
22 ## (e.g., Solaris, Irix) won't correctly propagate variables that are
23 ## defined in Makefile. This particular variable can't be correctly
24 ## defined by configure (at least, not the current configure), so we
25 ## simply avoid defining it to allow the user to use this feature with
29 ## Shell code that determines whether we are running under GNU make.
30 ## This is somewhat of an hack, and might be improved, but is good
32 am__is_gnu_make = test -n '$(MAKEFILE_LIST)' && test -n '$(MAKELEVEL)'
34 ## Shell code that determines whether the current make instance is
35 ## running with a given one-letter option (e.g., -k, -n) that takes
36 ## no argument. Actually, the only supported option at the moment
37 ## is '-n' (support for '-k' will be added soon).
38 am__make_running_with_option = \
39 case $${target_option-} in \
41 *) echo "am__make_running_with_option: internal error: invalid" \

46 sane_makeflags=$$MAKEFLAGS; \

49 ## variable $(MFLAGS) behaves much better in that regard. So use it.

52 ## Non-GNU make: we must rely on $(MAKEFLAGS). This is tricker and more
53 ## brittle, but is the best we can do.
55 ## If we run "make TESTS='snooze nap'", FreeBSD make will export MAKEFLAGS
56 ## to " TESTS=foo\ nap", so that the simpler loop below (on word-splitted
57 ## $$MAKEFLAGS) would see a "make flag" equal to "nap", and would wrongly
58 ## misinterpret that as and indication that make is running in dry mode.
59 ## This has already happened in practice. So we need this hack.
61 ## Extra indirection with ${bs} required by FreeBSD 8.x make.
62 ## Not sure why (so sorry for the cargo-cult programming here).

77 ## GNU make 3.83 has changed the format of $MFLAGS, and removed the space
78 ## between an option and its argument (e.g., from "-I dir" to "-Idir").
79 ## So we need to handle both formats.
