Using   gcc-2.95.2.1
        autconf-2.13
        binutils-2.10.1
        gnu-make-3.79.1
        no UDK (UnixWare Development Kit)


Attempting to build on UnixWare 7.1.1, which is an
i586-sco-sysv5uw7.1.1 HOST.

>Description:

GCC has a bootstrap error when compiling the latest cvs:
  /gcc/libstdc++-v3/libmath/mathconf.h:205:7: #error "We need INFINITE_P"
 
   
Here's what I used to configure gcc:
-------------------------------------------------------
../gcc/configure --enable-threads --enable-shared --enable-languages=c++ --with-as=/usr/bin/as
------------------------------------------------------








Here's what I saw when I after I typed
 gmake bootstrap

Thank you for looking at this, and I'd be glad to
provide more info if needed.

>How-To-Repeat:

This was noted too, in a post last year by Robert Lipe to
libstdc++@gcc.gnu.org that he has the same error.
