dbdimp.c fails to compile

[Rainer J.H. Brandt]

Hi,

I'm trying to build DBD-Pg-2.17.1 for Postgres 9.0.1 and Perl 5.12.2
on Solaris 10u8 i386 with Sun Studio 12u1.
dbdimp.c fails to compile.

The error is:

"dbdimp.c", line 61: identifier redeclared: lo_import_with_oid
        current : function(pointer to struct pg_conn {}, pointer to char, 
unsigned int) returning unsigned int
        previous: function(pointer to struct pg_conn {}, pointer to const char, 
unsigned int) returning unsigned int : 
"/opt/BBCpostgresql/9.0.1/include/libpq-fe.h", line 533
cc: acomp failed for dbdimp.c
*** Error code 1
make: Fatal error: Command failed for target `dbdimp.o'
Exit 1

Does anyone know a workaround?

Thanks,
Rainer
