Hello Paul,
we updated tools.ini for this error
localtime.obj : error LNK2019: unresolved external symbol S_ISREG
referenced in function tzloadbody
strftime.obj : error LNK2001: unresolved external symbol S_ISREG
zdump.exe : fatal error LNK1120: 1 unresolved externals
which is not resolved by the new patch.
I attached tools.ini.
Kind regards
Manuela Friedrich
