src/timezone/pgtz __imp__my_exec_path

beta4 - cygwin:
postgres.exe fails to build, because __imp__my_exec_path from 
src/timezone/pgtz.o cannot be resolved. previously it was not imported.

dlltool --dllname postgres.exe --output-exp postgres.exp --def postgres.def
gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wendif-labels 
-fno-strict-aliasing -L../../src/port -L/usr/local/lib  -o postgres.exe 
-Wl,--base-file,postgres.base postgres.exp access/SUBSYS.o 
bootstrap/SUBSYS.o catalog/SUBSYS.o parser/SUBSYS.o commands/SUBSYS.o 
executor/SUBSYS.o lib/SUBSYS.o libpq/SUBSYS.o main/SUBSYS.o

-lcrypto -lz -lreadline -lcrypt -lresolv
../../src/timezone/SUBSYS.o(.text+0x2192):pgtz.c: undefined reference to 
`__imp__my_exec_path'

nm postgresql-8.0.0beta4/src/timezone/pgtz.o |grep my_exec
          U __imp__my_exec_path
but:
nm postgresql-8.0.0beta3/src/timezone/pgtz.o |grep my_exec
          U _my_exec_path

The makefile didn't change. The src, cmdline and def file is also the 
same. It might related to some change in the header files with the 
pgport_srv seperation.
Can somebody give me a hint?
