Duplicate Symbols - Compiler Warnings

Greetings:

We are converting from 7.4.19 to 8.3. While compiling our application using
version 8.3, I have noticed the following warning from the compiler when
compiling perlAPI.c:

gcc -ggdb -Wall -Wmissing-prototypes -Wmissing-declarations -fforce-addr
-DUNIX-DSTDERR_MSG -D_REENTRANT -D_GNU_SOURCE -DDEBUGGING
-fno-strict-aliasing -pipe-I/usr/local/include -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm
-I/usr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE -I/usr/X11R6/include
-I/usr/local/pg83/include -I/usr/local/pg83/include/server
-I/esc/logpro/4.0/pgrnd/prog -c utility/perlAPI.c

from utility/perlAPI.c:11:
/usr/lib/perl5/5.8.5/i386-linux-thread-multi/CORE/config.h:2183:1: warning:

from utility/perlAPI.c:11:
/usr/local/pg83/include/postgresql/server/c.h:94:1: warning: this is the
location of the previous definition

In config.h, the symbol in question on line 2183 is:
#define _(args) args

In c.h (postgres) the offending symbol on line 94 is:
#define _(x) gettext((x))

I expect this to cause random core dumps when putting the application into
production and it concerns me greatly. So, my question is, do you see this as
a serious problem and, if so, what shall I do to resolve it? By the way, this
problem does not exist when compiling with 7.4.19.

TIA
