Troubles at building PostgreSQL with MinGW

Hi all!

I installed MinGW with MSYS on Win32 platform and attempted to build
PostgreSQL 8.3.0.

While ./configure --without-zlib has been passes successfully, the buld
has been failed. The error is shown below:

./make
...
make[3]: Entering directory
`/f/postgreSQL/postgresql-8.3.0/src/backend/utils/mb/conversion_procs/utf8_and_euc_jis_2004'
make[3]: *** No rule to make target `utf8_and_euc_jis_2004.o', needed by
`libutf8_and_euc_jis_2004.dll'. Stop.
make[3]: Leaving directory
`/f/postgreSQL/postgresql-8.3.0/src/backend/utils/mb/conversion_procs/utf8_and_euc_jis_2004'
make[2]: *** [all] Error 2
make[2]: Leaving directory

make[1]: *** [all] Error 2
make[1]: Leaving directory `/f/postgreSQL/postgresql-8.3.0/src'
make: *** [all] Error 2

Could anyone explain me what is wrong?

Thanks, Vlad
