Running the current CVS version under Windows with the "-n" (--dry-run)
option against the following example makefile:
all:
@echo hello
@echo there
...will leave two batch files in the TEMP directory each time it is run.
Running without -n properly cleans up the files.
The problem appears to be that "construct_command_argv_internal" (job.c,
lines 2769 and on) creates and writes batch files for shell commands
regardless of the "-n" option. However, with "-n", the shell is never
invoked, and so the batch files are never cleaned up on process
termination. Note that this is not a recent regression; make-3.80 exhibits
the same problem.
Should batch file creation be conditional on the "just_print_flag" value?
Related to this, could someone kindly explain why the above sample commands
are passed via batch files at all, instead of by invoking "cmd /c echo
hello" directly?
