Description:
i want to start building a project with ./configure --prefix=... $(myflags)
where myflags is an executable text file on my path. myflags has the
following in it:
printf 'CFLAGS="-O2 -fomit-frame-pointer" '
printf 'LDFLAGS="-Wl,-O2"'
now, when i do that ./configure complains for not recognizing
-fomit-frame-pointer option, and actually word splitting of bash ruins
what i wanna do. i want the word splitting of a command substitution
"to be careful about the quotes in the resulting expansion". is that
possible?

note: i have xubuntu 8.04 amd64 desktop, on a core2 dell laptop.

Fix:
something like $(command@) can be added to bash, retaining old
functionality. the new one will warn (somehow) word splitting to be
careful about possible quotes in the resulting expansion of the
command substitution.
