error: variable ‘ret’ set but not used

[GoogleCodeExporter]

Answering the following questions is a big help:

1. What version of distcc are you using (e.g. "2.7.1")?
3.2rc1

2. What platform are you running on
CentOS 6.4
gcc 5.1.0

3. What were you trying to do
install distcc

4. What went wrong?
compiler error
gcc -DHAVE_CONFIG_H -D_GNU_SOURCE 
-DSYSCONFDIR="\"/usr/local/modulefiles/../distcc/3.2rc1/etc\"" 
-DPKGDATADIR="\"/usr/local/modulefiles/../distcc/3.2rc1/share/distcc\"" -Isrc

[-Werror=unused-but-set-variable]
     int ret;

5. If you have an example of a compiler invocation that failed, quote it, in 
full e.g.:
   distcc gcc -DHAVE_CONFIG_H -D_GNU_SOURCE -I./src \ "-DSYSCONFDIR=\"/etc/\"" -I./lzo -g -O2 -W -Wall -W \ -Wimplicit -Wshadow -Wpointer-arith -Wcast-align \ -Wwrite-strings -Waggregate-return -Wstrict-prototypes \ -Wmissing-prototypes -Wnested-externs -o src/clirpc.o \ -c src/clirpc.c

6. What error logging do you get?

7. If you got an error message on stderr, quote that error exactly.
