compile error of cvs-1.10 on Solaris-7

[Jin Zhao]

When building cvs-1.10 on Solaris-7, the compiler always give errors of
conttents of server.c.
I tried different dowload methods and diffrent version of gcc, but the
error always happen. However, cvs-1.10-5 build smoothly. I look at the
code in server.c, it looks ok. I just wonder
what happens in cvs-1.10. 

Anybody has good idea ?

Thanks.

The following are what I did:  
gcc: 2.92 and 2.81 (I tried both)
make: 3.78.1 
configure --disable-server
errors:
