[sr #110395] Makefile generated from Makefile.in unqoute *FLAGS variable twice while ./configure script only once

[Zack Weinberg]

Update of sr#110395 (group autoconf):

Priority:   5 - Unprioritized => 2 - Eventually

Follow-up Comment #1:

I am inclined to say that *FLAGS should be unquoted only once. However, it is
not obvious to me whether this means the bug needs to be addressed in
Automake, or whether this means config.status needs to *put back* some quoting
so that Automake's existing code does the right thing.

Postponing until someone has time to have a conversation with the automake
people and decide what is the best approach.

Details:

For the following scenario it's impossible to provide correct CFLAGS with
attached configure.ac, Makefile.am, and main.c files.

You must use +CFLAGS='-DSTRING="string"'+ to pass +AC_COMPILE_IFELSE+ test
from configure.ac, but to provide same macro value to main.c you should use
+CFLAGS='-DSTRING=\"string\"'+.

As result we have the current situation:
> ./configure CFLAGS='-DSTRING="string"' && make # Fails on compilation
> ./configure CFLAGS='-DSTRING=\"string\"' && make # Fails on configuration
