You mean the 35 instances of "HAVE_UNEXEC" in C source files, not excepting the "HAVE_PDUMPER || HAVE_UNEXEC" conditions, or the malloc and Gnulib flags that aren't necessary on unexsol? I would be as glad as you to see most of them removed, as they are not significant on the systems where unexec should be retained. > If you intend to work on modifying the unexec code to not use pure > space, don't waste your time: I will object to any serious development > of the unexec code. The only way forward for the platforms that > currently need unexec is to start using pdumper. I need not modify the unexec code, or adapt it to configurations without pure space, as there simply is no code to adapt. unexsol.c works _now_ with or without pure space, and I would be immensely surprised if the same were not true of DJGPP, and as it happens, whether in Emacs or elsewhere. > Once again, it is immaterial when a platform was EOLed. That is not > the reason why we want to drop unexec. That's not what I heard just one message removed from mine, where being two years from EOL was stated to be sufficient grounds to withdraw support.
