[Dovecot] Problem compiling antispam plugin with Dovecot 1.1

[Juan Asensio Sánchez]

Hi

I am trying to compile antispam plugin with Dovecot 1.1, but i get an
error when running make install:

pdc-server:~/tmp/dovecot-antispam# make
cc -c  -DHAVE_CONFIG_H -Wall -I/root/tmp/dovecot-1.1.rc5/
-I/root/tmp/dovecot-1.1.rc5/src/ -I/root/tmp/dovecot-1.1.rc5/src/lib/

When running make clean to try to compile again, a file called
"antispam-storage-1.1.c" (without any extension) is not deleted, and
this file was not before running make install. If I run again make
install with that file present (after running make clean), i get this
output:

cc -c  -DHAVE_CONFIG_H -Wall -I/root/tmp/dovecot-1.1.rc5/
-I/root/tmp/dovecot-1.1.rc5/src/ -I/root/tmp/dovecot-1.1.rc5/src/lib/

cc      -o .o

If I run make clean and manually deleted that file before running make
install, i get again the first output. Why am i getting this error?

Regards.
