Hello,
The help text produced by autoconf is part specific to our scripts and
part is standard autoconf stuff. The variable section is part of the
standard help. It's bad that the script isn't behaving as the help text
suggests and we should try to fix that if possible. We definitely need
to review the documentation.
We have avoided letting environment variables affect configure. The
reason is reproducibility, we want to force configuration options to the
command line so that it's obvious someone put them there for a reason,
rather than something hidden in the environment secretly changing
things. For this issue I'm not sure which would be the best solution. It
could use some discussion.

David,
I could be mistaken but I thought the use of CXX= was intended as a make
variable to override the value that configure places in the spec.gmk file - not
as a way to force configure to output something to spec.gmk.
It's entirely likely that I misunderstood, but I think the output of "sh ./configure
-help"
could be made less ambiguous. I would ordinarily expect "make help" to inform
me of
relevant EVs for running make.

Running generated-configure.sh
`configure' configures OpenJDK jdk8 to adapt to many kinds of systems.
Usage: ./common/autoconf/configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
...
(below)
Some influential environment variables:
PKG_CONFIG path to pkg-config utility
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory<lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory<include dir>
CXX C++ compiler command
CXXFLAGS C++ compiler flags
OBJC Objective C compiler command
OBJCFLAGS Objective C compiler flags
CPP C preprocessor
CXXCPP C++ preprocessor
XMKMF Path to xmkmf, Makefile generator for X Window System
FREETYPE2_CFLAGS
C compiler flags for FREETYPE2, overriding pkg-config
FREETYPE2_LIBS
linker flags for FREETYPE2, overriding pkg-config
ALSA_CFLAGS C compiler flags for ALSA, overriding pkg-config
ALSA_LIBS linker flags for ALSA, overriding pkg-config
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
