I used Eli's suggestion to fix the ENOTSUP problem and found another #define deficiency This time, the build crashed wen compiling gcc8.1.0/gcc/pretty-print.c. There is a new Windows-specific addition her, and it has two undefined constant problems: COMMON_LVB_UNDERSCORE COMMON_LVB_REVERSE_VIDEO A bit of web searching quickly revealed that these are documented in Microsoft's online documentation. The actual numeric values are documented. They should be in wincon.h: For now, I have hacked the definitions into the pretty-print.c source code using Eli's ENOTSUP fix as a model. That seems to be tha last of the definition failures. The build crashed at the point where it compared the stage 2 and stage 3 binaries: Comparing stages 2 and 3 warning: gcc/cc1obj-checksum.o differs warning: gcc/cc1objplus-checksum.o differs The 7.3.0 build produced the same warning, but the 8.1.0 build crashed immediately after that warning: make[1]: *** [stage3-bubble] Error 58 I'm still investigating that. But, back to wincon.h. There is a lot of detailed documentation on the Microsoft documentation web site, complete with values for constants that can go into wincon.h, and it is all publically documented, so I am now working on a rebuild of wincon.h, which is the best solution for the gcc build failure.
