[petsc-dev] CFLAGS / LDFLAGS and cxx error

It's a good question.  I found myself completely overwhelmed by the
./configure --help output.  I'm wondering if there's a way to
partition it into smaller subsections similar to how gdb's help has
different help sections depending on whether you're setting
breakpoints, examining a backtrace, etc.  petsc is compiling right
now, so when it's done, I'll have a look at the descriptions for
CFLAGS and CXXFLAGS.  Posting the reason for the cxx compiler not
being recognized would definitely help.
