Windows 64-bit Build Support
Adds native Windows 64-bit compilation support using MinGW-w64 gfortran. All 13 HOLE2 executables build and run successfully.
Changes
src/machine_dep.win64dateshell call withDATE_AND_TIME()intrinsic;DTILDA()is a no-opsrc/build_windows.ps1src/cguess.fDO RCOUNT=-5.,5.,1.) which causes a silent crash in gfortran 16 on Windows; fix is standards-compliant on all platformssrc/hp_flush.cflush_()alias for gfortran name-mangling on WindowsREADME_windows.mdHow the Linux build is unaffected
The build script copies
machine_dep.win64→machine_dep.fbefore compiling. The existingmachine_dep.g77and the Makefile are untouched. Thecguess.ffix is backward-compatible.Tested
Closes #16
