[hobbit] Need HELP! Compile errors! Solaris 10

[David Gore <David.Gore (at) mci.com>]

Unfortunately after upgrading to solaris 10 we have had some 
difficulties, just running hobbit causes the server to become 
unresponsive including from the console.  So I thought I should do a 
recompile which ends like so...

gcc -g -O2 -Wall -Wno-unused -D_REENTRANT -DHAVE_RPCENT -DSunOS 
-DMAXMSG=32768 -DBBDPORTNUMBER=1984 -I. 
-I/var/tmp/hobbit-4.0.3rc2/include -I. -I../include    -c -o misc.o misc.c

Any ideas?
