[Linrad] Re: New version: linrad-02.48

Hi Leif,

When I compile Linrad-02.48 in ubuntu 8.04 with oss I get problems in
lsetad.c :

*************************
lsetad.c: In function âlir_tx_adreadâ:
lsetad.c:519: warning: unused variable âerrâ
lsetad.c: In function âthread_rx_adinputâ:
lsetad.c:558: warning: unused variable âerrâ
lsetad.c: In function âthread_test_rxadâ:
etc
***************************
Looks like a number of  #ifdef ALSA_PRESENT statement are not on the
right line.

When I compile with native alsa everything runs fine.
