But unfortunately it is not done that way. Instead we have

Makerules.gcc:  @$(CC) -MM $(CPPFLAGS) $(CFLAGS) -o $@ $<
Makerules.gcc:  @$(CC) -c $(CPPFLAGS) $(CFLAGS) -o $@ $<
Makerules.gcc:  @$(CXX) -c $(CPPFLAGS) $(CXXFLAGS) -o $@ $<
Makerules.gcc:  @$(AS) -c $(CPPFLAGS) $(ASFLAGS) -o $@ $<
Makerules.gcc:  @$(AR) $(ARFLAGS) $@ $?

plus

Makerules.all:  @-rm -f $(SRCS:.c=.bak)
Makerules.all:  @-rm -f $(SRCS:.c=.c~)
Makevars.all:CP = @cp
Makevars.gcc:AR     = @$(TRGT)ar
Makevars.gcc:CP     = @cp
Makevars.gcc:RM     = @rm -f

Still no big deal to change them, but I have to do this after each checkout.

How about using

 make >NUL

in your script? Btw. if using scripts, you can do more. The Lua script that builds the Windows distribution, collects all errors with some additional information in a special log. As an example (trying to build the current trunk):

This gives a nice overview about all unsolved problems. Of course you could do something similar with DOS batch files or shell scripts.

As a side effect of the "@" silencing, this script also does no longer list the command line, which sometimes contained valuable informations, specifically when adding new devices.

Do you remember, where you needed to add this? Just curious, because I'm using "make burn" (without recompiling) for years.
