[bash] command line substitution with environmental variables
Hi,

I'm using an array that contains compiler FLAGS
that need to be executed either before ./configure
or after the main 'make' command.

example of array containing compiler flags.
-------------------------------------------------
Code:
FLAGS[0]="CFLAGS=\"-arch x86_64 -g -Os -pipe -no-cpp-precomp\""
FLAGS[1]="LDFLAGS=\"-arch x86_64 -bind_at_load\""

To get the output:
CFLAGS="-arch x86_64 -g -Os -pipe -no-cpp-precomp" LDFLAGS="-arch x86_64 -bind_at_load" ./configure

Unfortunately, when I try to use the usual substitution
$(${FLAGS[@]}), it seems to terminate after the first
space following the -arch option:

CFLAGS="-arch: command not found

I've tried a number of combinations but not been able
to find a conclusive solution. Any help or ideas would
be appreciated.

A.
