Bug 109

Hi,

Building Slony 2.0.2 or 2.0.3rc3 against PostgreSQL 8.4.2 on Snow Leopard fails
while compiling src/slony_logshipper/parser.c ...

gcc -g -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -I../..
-DPGSHARE="\"/opt/local/share/postgresql84/\"" 
-I/opt/local/include/postgresql84/ -I/opt/local/include/postgresql84/server/  
-c -o parser.o parser.c
In file included from parser.y:1101:
scan.c:161: error: conflicting types for 'yyleng'
parser.y:25: error: previous declaration of 'yyleng' was here
scan.c:288: error: conflicting types for 'yyleng'
parser.y:25: error: previous declaration of 'yyleng' was here

The OS is 10.6.2 and hardware is a 2009 Mac mini.  "uname -a" returns this
signature...

Darwin pratt 10.2.0 Darwin Kernel Version 10.2.0: Tue Nov  3 10:37:10 PST 2009;
root:xnu-1486.2.11~1/RELEASE_I386 i386

The same bug manifests under 10.6.2 on a 2005 MacBook.

This patch to src/slony_logshipper/scan.c applied *after* it's generated allows
the compilation to finish.  This is obviously a hack and I don't know yacc well
enough to fix it properly.
