I can reproduce this, once I uninstalled libtextstyle.
The problem is my call to

> gl_LIBTEXTSTYLE_OPTIONAL([0.20.5])
in configure.ac. First, it was too early (right after gl_EARLY) and it
generated
> TEXTSTYLE_H="${gl_source_base_prefix}textstyle.h"
before the definition of gl_source_base_prefix.
If I move it after gl_INIT, I get:

> gl_source_base_prefix='$(top_build_prefix)lib/'
> ALLOCA_H="${gl_source_base_prefix}alloca.h"

Both assignments to gl_source_base_prefix are baked in gl_INIT. This second
assignment is meant for the tests, it is from
> gl_COMMON
> gl_source_base='tests'
> gl_source_base_prefix=
This is probably affecting all the modules for which the user is expected to
call the macro by hand: the variables will not be set as expected.
I don't know what is the preferred fix here. Bruno?
