2429 # linker flag in LDFLAGS as well, or --with-aix-soname=svr4 only.

2433 # archive as well as the shared archive member, telling the

2435 # list of exported symbols of that shared object, eventually
2436 # decorated with the 'weak' keyword
2437 # *) the shared object with the F_LOADONLY flag set, to really avoid
2438 # it being seen by the linker.
