configure fails configuring i386-mingw32/libf2c

[giacomo boffi <giacomo dot boffi at polimi dot it>]

i'm hosted on a linux system, i have gcc-2.95.3 installed, and i'm
trying to build (in essence) i386-pc-mingw32-g77

i prepared the includes/libs

% cd $prefix ; tar xvzf ~/bin-crtdll-2000-02-03.tar.gz

i built and installed binutils, with

% ../binutils-2.9.1/configure --target=i386-mingw32
% make all install

and later i built and installed (mostly of) gcc

% ../gcc-2.95.3/configure --target=i386-mingw32 --enable-languages=f77,c++
% make all install

all went well (after some twiddling) so i tried to compile a test
fortran source, but the new g77 failed, as (the new) ld failed to find
libg2f.a

after inspection, i found that there was an almost empty
i386-mingw32/libf2c directory, with a config.log file that i include
below

it looks like that some headers aren't found by configure... it's
strange as the other libraries under i386-mingw32/ are built ok

here is the file, tia for your help
