I am having Problems installing libg++-2.2.  
I got everything to compile except 2 files from the iostream library.
I made libg++ without these two files but when I ran g++ I got the 
following error message:
ld:
Undefined:
vscan__9streambufPCcPcPUc
vform__9streambufPCcPc

Seems like I need to compile sbufvscan.C and sbufvform.C.
Can someone tell me how to compile these two routines.  I'm using 
gcc version 2.1 on a decstation 5000/240 running Ultrix v4.2a.  
( can version libg++-2.2 be used with gcc v2.1? ).   

I include the output of running make and the error messages.

Thanks Alot,
John O'Neill

PS Quick question, how can you tell what version of libg++ you are using?

Similiar problem with sbufvscan.C (comment out sbufvform.C)
