i was trying to test this and make a simple program based on the first
libpq example that only shows client_encoding
this little test compiles fine until i applied your patch :(
postg...@casanova1:~/pg_releases/pgtests$ gcc -o test-libpq
test-libpq.o -L/usr/local/pgsql/head/lib -lpq
/usr/local/pgsql/head/lib/libpq.so: undefined reference to
`pg_get_encoding_from_locale'
collect2: ld returned 1 exit status
just in case i attached the test program.
