What I have understood is that it's a matter of --disable-shared or
--disable-static during configure.

OK. What's happening now is that there is a libflower.la, flower using
the `library' stepmake rules, and liblilypond-bin-2.3.5.so (hidden in
lily/out/.libs/) and liblilypond-bin.la, lily using the
`shared-library' stepmake rules (which have to be re-written anyway,
as they mention libflower.la explicitely...)

flower and lily should be using the same rules, which would generate a
shared-library, adding -rpath and -revision (or -version-info?) flags
at the end of the `libtool --mode=link' command.

[hm, I'm just thinking loud, Jan, not explaining you things you
know :)]

There may be several directories:

 lily/
    MODULE_LIB_DEPS=flower
    NAME=lily
    STEPMAKE_TEMPLATES= c++ library po

 parser/
    MODULE_LIB_DEPS=flower lily     (?)
    NAME=lyparser
    STEPMAKE_TEMPLATES= c++ library po

 gui/    using the library rules
    MODULE_LIB_DEPS=flower lily     (?)
    NAME=lygui
    STEPMAKE_TEMPLATES= c library po

 XXXX/   using the executable rules
    MODULE_LIB_DEPS=flower lily lyparser lygui
    NAME=lilypond-bin
    STEPMAKE_TEMPLATES= c++ executable po help2man

I don't know well enough the C++ part to determine which should go
where in that case. maybe:

* parser/

includable-lexer.cc
lexer.ll
my-lily-lexer.cc
my-lily-parser.cc
parser.yy
parse-scm.cc
source.cc
source-file.cc
binary-source-file.cc
input.cc
keyword.cc

* gui/

pangofc-afm-decoder.cc

* XXXX/

main.cc

* lily/

all others.
