On my Red Hat 9 Linux system, with its Apache version 2.0.40-21, I tried
building "mod_scgi" using "make all"  from the "scgi-1.1" directory, and
got a boatload of errors.  I've copied the first few lines of output,
below. Judging from the errors, the include files are being found, but
there are apparently some symbols that can't be resolved, such as
"module" and/or "MODULE_VAR_EXPORT."  Any thoughts on how to make this work?
