Hi
We are using a code generator for initializing structures with the #define macro. Compiling it with the GCC 2.8.1 (with -ansi) it OK. But when we are using the SUN C 5.0 compiler it screams.
Following is a code sample:

PG_WRAPPER(1) Debian PostgreSQL infrastructure PG_WRAPPER(1)
NAME
pg_wrapper - wrapper for PostgreSQL client commands
SYNOPSIS
client-program [--cluster version/cluster] [...]
(client-program: psql, createdb, dropuser, and all other client programs installed in /usr/lib/postgresql/version/bin).
DESCRIPTION
This program is run only as a link to names which correspond to PostgreSQL programs in /usr/lib/postgresql/version/bin. It determines the
configured cluster and database for the user and calls the appropriate version of the desired program to connect to that cluster and
database, supplying any specified options to that command.
The target cluster is selected by the following means, in descending order of precedence:
1. explicit specification with the --host option
2. explicit specification with the --cluster option
3. if the PGHOST environment variable is set, no further cluster selection is performed. The default PostgreSQL version and port number
(from the command line, the environment variable PGPORT, or default 5432) will be used.
4. explicit specification with the PGCLUSTER environment variable
5. matching entry in ~/.postgresqlrc (see postgresqlrc(5)), if that file exists
6. matching entry in /etc/postgresql-common/user_clusters (see user_clusters(5)), if that file exists
7. If only one local cluster exists, that one will be selected.
8. If several local clusters exist, the one listening on the default port 5432 will be selected.
If none of these rules match, pg_wrapper aborts with an error.
OPTIONS
--cluster version/cluster
cluster is either the name of a local cluster, or takes the form host:port for a remote cluster. If port is left empty (i. e. you just
specify host:), it defaults to 5432.
ENVIRONMENT
PGCLUSTER
If $PGCLUSTER is set, its value (of the form version/cluster) specifies the desired cluster, similar to the --cluster option. However,
if --cluster is specified, it overrides the value of $PGCLUSTER.
PG_CLUSTER_CONF_ROOT
This specifies an alternative base directory for cluster configurations. This is usually /etc/postgresql/, but for testing/development
purposes you can change this to point to e. g. your home directory, so that you can use the postgresql-common tools without root
privileges.
FILES
/etc/postgresql-common/user_clusters
stores the default cluster and database for users and groups as set by the administrators.
$HOME/.postgresqlrc
stores defaults set by the user himself.
