alpha Tru64 config bug? DU 4.0b & 2.95

[Chad Price <cprice at molbio dot unmc dot edu>]

OS = Tru64 (osf) 4.0b. gcc being used for 2.95 is gcc 2.8.1

(1) gcc 2.95 alone builds fine using gcc 2.8.1

(2) g77 with gcc 2.95 does not finish the build:

config line:

./configure --prefix=/usr/local/stow-dir/gcc-2.95 --enable-languages=f77

configure runs to completion without any errors that I noticed.

Compile was simply
	make

The compile bombs here:


mv tmp-params.h _G_config.h
test x"no" != xyes || /usrdata2/local/src/gnu/gcc-2.95/gcc/xgcc
-B/usrdata2/local/src/gnu/gcc-2.95/gcc/

                  from iolibio.h:1,

                  from filedoalloc.c:45:
_G_config.h:2: unterminated `#if' conditional
*** Exit 1
Stop.
*** Exit 1
Stop.
#

The contents of _G_config.h look like this:


/* AUTOMATICALLY GENERATED; DO NOT EDIT! */
#ifndef _G_config_h
#define _G_config_h
#define _G_LIB_VERSION "2.8.0"


Seems like the #endif  is being left out. This is replicatable.  It does 
not occur when config is run with "--enable-languages=c" but as soon as I 
use "--enable-languages=c,f77"  or "--enable-languages=c,c++,f77"  The 
error occurs.

If c++ is not built and I try to build g77, on the lines immediately above, 
I also get:
