I don't have access to any other systems that have the 2.04.0 version of
bash.  Every test I tried had the same results. Expressions like:
    (: ${SAVE_CFLAGS?})
always had a 0 exit status for me in this version.  For the version I've
been compiling, I have LAME in a nonstandard directory and I specify it
in the CFLAGS.  This problem caused the CFLAGS to be lost and the
configuration script would always fail trying to the LAME headers/libs.

Bash >= 2.05b seems to be fine.  AFAIK, MinGW comes with 2.04.0 as,
but 2.05b package an be downloaded from MinGW's website.
