The patch: https://gerrit.libreoffice.org//25673/ has an error on Windows (patch set 42): LINK : fatal error LNK1181: cannot open input file 'tommath.lib' I think it's because I created tommath.lib using the ar linux command, and the result is slightly different from the .lib file that msvc expects.[1][2] I would have liked to use lib.exe to create tommath.lib instead, which seems to be the tool on Windows to create a .lib file, but I couldn't find the appropriate makefile marco to use it (like the LD variable stores the path of link.exe), since the variable AR stores "ar" in case of Windows too. Am I right about the cause of the issue, and if so, how can I refer to lib.exe to use it for creating tommath.lib?
