>Description:
Using a 1.3.2 toolchain I can cause the following nightmare:

rigel# c++ test.c -lossaudio
test.c: In function `int main()':
test.c:6: warning: implicit declaration of function `int Setvolume(...)'
test.c: In function `int Setvolume(int)':
test.c:25: warning: implicit declaration of function `int close(...)'
/var/tmp/cc18393a1.o: In function `main':
test.c(.text+0x1c): undefined reference to `Setvolume'
test.c(.text+0x20): undefined reference to `Setvolume'
/var/tmp/cc18393a1.o: In function `Setvolume(int)':
test.c(.text+0xe0): undefined reference to `_oss_ioctl(int, unsigned long, void *)'
test.c(.text+0xe4): undefined reference to `_oss_ioctl(int, unsigned long, void *)'
test.c(.text+0x108): undefined reference to `_oss_ioctl(int, unsigned long, void *)'
test.c(.text+0x10c): undefined reference to `_oss_ioctl(int, unsigned long, void *)'

rigel# gcc test.c -lossaudio
rigel# 

As you can see, test.c linked with ossaudio under gcc works just fine, and
"as planned".  Trying to do the same thing with c++ causes undefined references
to perfectly valid calls within the library.  

	
>How-To-Repeat:
this tiny little snippet will jiggle the problem when compiled:
c++ foo.c -lossaudio

#include <soundcard.h>
main(){_oss_ioctl(1,1,1);}

compile with gcc foo.c -lossaudio to see the proper behavior.

(dont even try to run it, for obvious reasons)

Ummm...  ENOCLUE.
