It just won't run correctly anymore on W7/8, because - the special treatment required for those OSes isn't in the DLL anymore, and - the DLL uses functions not available on these OSes.

Are you saying that W7 and W8 would be actively rejected? Supporting older OSes requires to keep workarounds in the code and sometimes leads to the inability to implement stuff in ways only available on newer OSes. Each deprecation of older OSes in Cygwin worked like this so far, and for 3.5 (late 2023) we announced the deprecation of Windows 7 and 8 since the first 3.3.0 release in October 2021.

Automated builds have been picked up again and the Cygwin test package 3.5.0-0.17.g95f5b0a62036 should be available later today. You can install it using setup.exe, just like any other test release. Don't forget to install the matching cygwin-devel package, too, that's the one containing the library libgmon.a, which is what gets linked in with `gcc -pg'.

Thanks for the report. This is a dumb bug I introduced into the build system in 3.4.0. I fixed that in the git repo, but the automated build of the matching test release cygwin-3.5.0-0.17.g95f5b0a62036 is currently not building due to some hiccup on cygwin.com. I'll send a new mail as soon as this is fixed and you can test it (provided you run at least Windows 8.1).

gcc -pg broken after cygwin update?
Hi, This morning I updated cygwin, and after that gcc started producing errors like this: > gcc -Wall -Wextra -Werror -pedantic -Wno-unused-parameter -g -pg -DVERBOSE > -c -o ../obj/.o .c > gcc -o ../bin/ ../obj/.o -pg > /usr/lib/gcc/x86_64-pc-cygwin/11/../../../../x86_64-pc-cygwin/bin/ld: > ../obj/.o: in function `exit_eval_failure': /home/daab/dev/someproj/src/.c:17: undefined reference to `__fentry__' If I drop the "pg" flags from the compilation and linking stages, everything works. I typically update cygwin packages once per week, but now it has been maybe a month since I last updated. As far as I can tell from the cygwin-announce archives, there has not been any gcc updates in that period, but I do note that cygwin itself has been updated. Could that be related?
