Strange Behavior with compiling

[Pete Willemsen <willemsn@cs.uiowa.edu>]

Hello.

I'm using automake and autoconf in the development of a project I'm
working on.  They are working great if I don't use the EGCS compilers. 
I'm really not sure what is going on, but I thought I would pose my
problem and see if others had any ideas.

I have my configure.in script set to use CXX=CC and CXXFLAGS="-n32 -O2"
since the majority of my development is on an IRIX system.  This works
fine.

I also have my configure.in script set up to let me override CXX and
CXXFLAGS in a normal manner by setting environment variables. 
Sometimes, I compile my code (on SGI IRIX and Linux) using the EGCS
compilers.  When I set CXX=c++ and CXXFLAGS="-O2 -Wall", run configure,
and then try to compile, I get the following result:

--------
Making all in libarts
make[3]: Entering directory `/home/willemsn/Research/hank/src/libarts'
c++ -DHAVE_CONFIG_H -I. -I. -I../.. -I../../include    -O2 -Wall -DLINUX
-c sema.C
Usage: cpp [switches] input output
Switches:
  -include <file>           Include the contents of <file> before other
files
  -imacros <file>           Accept definition of marcos in <file>
...
  -remap                    Remap file names when including files.
  -h or --help              Display this information
cpp: Too many arguments
make[3]: *** [sema.o] Error 1
--------

I can't see what's wrong with the compile command.  In fact, if I cut
and paste the "c++ -D..." line above at a shell prompt everything works
out fine.

I get this behavior both on the IRIX system and on the Linux system when
I use the EGCS compilers (I only have EGCS on my Linux box).

Has anyone else noticed anything like this?  Does anyone have any ideas?

Many thanks for your time!
