Обсуждение: mingw initdb failure on HEAD

Several buildfarm mingw members are getting failures like this, when 
running initdb:
   creating conversions ... FATAL:  could not load library
"C:/msys/1.0/home/pgrunner/bf/root/HEAD/pgsql.3584/src/test/regress/./tmp_check/install/home/pgrunner/bf/root/HEAD/inst/lib/postgresql/utf8_and_johab.dll":
Invalidaccess to memory location.          STATEMENT:  CREATE OR REPLACE FUNCTION johab_to_utf8 (INTEGER, INTEGER,
CSTRING,INTERNAL, INTEGER) RETURNS VOID AS '$libdir/utf8_and_johab', 'johab_to_utf8' LANGUAGE C STRICT;          child
processexited with exit code 1     
 

See for example 
<http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=dawn_bat&dt=2010-05-27%2019:45:18>

Could it have been caused by the PGDLLIMPORT/PGDLLEXPORT changes?

cheers

Probably, but it's curious because MSVC members are OK.
Do we have special treatments for exported functions in mingw?
It might export 'dllimport' funtions/variables, but not 'dllexport' ones.

It has broken Cygwin as well, so that's two out of three Windows 
platforms that don't like this.

I am not sure what the best fix for the original problem is, but this 
isn't it.
