compilation problem with -fno-exceptions

[Pasha Murat (630)840-8237 FNAL (630)859-3463 home]

Dear GCC developers,

I just built todays version of gcc grabbed from the repository
on RH 6.1 Linux box. I managed to build all the binaries, however 
to do it I had to jump over a couple of hurdles:

- for some reason `make' on my box didn't recognize an old pattern
  rule `.c.o:' in libiberty subdirectory (however it did recognize
  the same rule in other subdirs), had to replace it with `%.o:%.c'
- when building libstdc++ I had to patch manually few makefiles
  to replace `libtool' with `libtool --tag CXX'

OK, then the c++ compiler bails out when asked to compile a pretty 
simple test example (see below, output enclosed) with disabled 
exceptions. However it successfully compiles and links it when
exceptions handling is enabled (default switches).

Am I doing something wrong? How one could configure gcc 2.97 to stay
with disabled exceptions?
				thanks a lot, Pasha
