Error when building R (89301+) on Windows 11 - but not every platform

You should scan the complete log for error messages. That a PDF was 
produced does not imply there were no errors (pdflatex is run with 
-interaction=nonstopmode), but a non-zero exit code usually means there 
were.

Line 127 in /trunk/doc/manual/Makefile.win is
opt="$(R_RD4PDF)"; \

This is probably unrelated. Maybe the reported line number does not 
match the "physical" lines in the Makefile because some recipe lines are 
split. I believe the error happens in the first pdflatex run. You could 
call make with --trace to see more (force printing the recipe lines 
during execution), but you should really check the LaTeX log. I guess 
there is a problem with one of your LaTeX installations.
