libosmocore/osmocombb build error

[Job]

Hi,

While working on a patch I noticed an autoconf error in libosmocore:

$ autoreconf -i
Makefile.am:20: docdir was already defined in condition TRUE, which
includes condition HAVE_DOXYGEN ...
configure.ac:1: ... `docdir' previously defined here

using autoconf 2.67 and automake 1.11.1

My autoconf knowledge is limited, but could it be that docdir is
autogenerated from including doxygen or something?

configure has docdir now defined as
--docdir=DIR            documentation root [DATAROOTDIR/doc/libosmocore]

which is different from the requested define in Makefile.am:
docdir=$(datadir)/doc

Best regards,

Job
