Some previously built object files were no longer recognized as such, and halted the build; even file showed them as generic "data". This persisted even after rm **/config.cache, plus those object files not showing as "Intel 80386 COFF object file", and redoing ./configure && make. Only after doing "make distclean", rm **/config.cache, ./configure && make, did the build complete normally. Any ideas what the issue might have been, and best practices for rebuilding cygwin after tool updates? -- Take care.
