An ugly way to do it on Unix platform would be:

$ make VERBOSE=1 > compile.out

this will print the error on stderr (if any)

then
$ tail compile.out | grep -A1 "\\[.*%"

will give you the last failiing compile line.

if you want to keep the progress report, you may enhance the first command with:

$ make VERBOSE=1 | tee compile.out | grep "\\[.*%\\]"

I assumed you were on Unix + Makefile + command line and this
is just a trick waiting for your may-be feature request to be may-be
implemented :-)
