When running make in geant4_5_2/source/ directory (using cygwin 1.14-1 in Windows 2000) an error is issued: '[' is not recognized as an internal or external command, operable program or batch file. It appears that error is generated at the line: G4DUMMY_VARIABLE:=$(shell [ ! -d $(G4TMP) ] && mkdir -p $(G4TMP) ) in geant4_5_2/config/architecture.gmk file.
Upgrade to cygwin 1.5.5-1 solved the problem. Something was wrong with previous cygwin installation
The problem is now closed.
