Theoretically, that should have worked (did you export that
variable?). But curl has some autoconf macros (in m4/curl-compilers.m4)
that try to detect the compiler being used and play with some of the
flags, including the debug flag. If the compiler is supported (and
Solaris appears to be) the giving the --enable-debug configure option
should be enough to have -g added automatically.
