Similar lines appear in the gcc/config.log from a GCC 3.3.3 build:

configure:4461: checking whether strsignal is declared
configure:4480: gcc -c -g -O2 -I../../gcc -I../../gcc/../include  conftest.c 1>&5
configure: In function `main':
configure:4475: error: `strsignal' undeclared (first use in this function)
configure:4475: error: (Each undeclared identifier is reported only once
configure:4475: error: for each function it appears in.)

However, 3.3.3 will successfully bootstrap.

It looks like the problem is that the configure and build are done with 
different compiler options.  The configure is done with "gcc".  The 
build is done with "gcc -D__INTERIX -D_ALL_SOURCE".  This is not wise, 
as it means the configure checks will not be correct for the build.  You 
must use the same compiler (and compiler options) for configure and build.

Probably strsignal is in /usr/include/string.h, but only declared if one 
of __INTERIX or _ALL_SOURCE is defined.  Thus the configure check did 
not see it, but the build did.

gcc-3.4 behaves differently than gcc-3.3 here because the 
HAVE_DECL_STRSIGNAL stuff in system.h is new.  This adds a declaration 
if strsignal is present in libc, but we found no declaration in the 
header files at configure time, which is the case here.

This is a bug with the gcc/config/x-interix file.  It sets X_CFLAGS, 
which won't work, because this modifies the compiler flags after we have 
already configured.

I have no good immediate suggestion on how to fix this.  Maybe it can be 
hacked around in an xm-interix.h file by defining HAVE_DECL_STRSIGNAL. 
That is an ugly solution though.

OK, well I can just do a 'export CFLAGS="-D_ALL_SOURCE"' before bootstrapping
and it seems that will be OK as a workaround.  However, now I've bumped into the
problem  with test_real_width which was described on the GCC maillist here:
http://gcc.gnu.org/ml/gcc/2004-04/msg01110.html

So I guess the next question is, how do I go about petitioning those patches be
integrated into the GCC source tree?

The patches have to be submitted to gcc-patches.  Also, we need 
copyright assignments from the author(s) if the patches are non-trivial. 
  I see no actual patches in the thread you referred to, it just 
mentioned that patches were available from Microsoft.

I've uploaded the patches here:
http://www.beatware.com/~tristan/Interix/interix-patches.tar.gz

There were actually two directories of patches in the Microsoft-supplied
tarball; I wasn't sure of the differences so I included both.

I'm taking a look at this.  Since I don't have interix, I need help from the 
bug reporter. 
 
Could you try the following?  Replace the gcc/config/x-interix file with an 
empty file (or a file just containing comments), and try bootstrapping.  
Attach the log. 
 
Please try on mainline CVS if possible.  Thanks.

I've now set up an Interix system for the purpose of providing shell accounts. 
Anyone who would like access for testing/development of GCC should email me and
I'll create an account for them.
