# configure/make, and can't include it as a noinst_ library. Libtool

# assumes that such libraries will be installed along with our library

# included in ours - despite the fact that we are making a shared

# library and linking to a static one. This is broken and we work
|

|
|
# around it by hacking the whole-archive flags into the _LDADD variable
|

|
|
# for wallycore.

# Because automake tries to police its users very strictly and fails
|

|
# hard when flags are passed in this way, we have to substitute the

# flags here.
|

# Because libtool both intercepts -Wl and arbitrarily re-orders its

# command line inputs, we have to concoct a single expression to

# enforce linking that cannot be split, hence the below expression.
