6# Before main.c 1.421 from 2020-11-01, make exited successfully even though
7# the error message had been issued as PARSE_FATAL.  This was because back
8# then, make checked for parse errors only after parsing each top-level
9# makefile, in Parse_File.  After that, when expanding expressions
10# in shell commands, the parse errors were not checked again.

12# Ouch: as of 2020-08-03, the variable is malformed and parsing stops
13# for a moment, but is continued after the wrongly-guessed end of the
14# variable, which echoes "y@:Q}".
