Hello
I ran into the following 2 problems when trying to build gcc-2.95.3-5 on
cygwin and gcc-3.0.  Both gave me the same problems in the same file.  Below
is how i got it to compile but I sure my implementation is probably wrong.
Here goes.
********
error 1:
********
in file:
<gcc_source_directory>/libiberty/strerror.c
../../gcc-2.95.3-5/libiberty/strerror.c:464: conflicting types for
`sys_errlist
/usr/include/sys/errno.h:23: previous declaration of `sys_errlist'
make[1]: *** [strerror.o] Error 1

original:
static const char **sys_errlist;
fix:
//static const char **sys_errlist;
(commenting out the declaration fixes this)

error 2:
********
in file:
<gcc_source_directory>/libiberty/strerror.c
../../gcc-2.95.3-5/libiberty/strerror.c
../../gcc-2.95.3-5/libiberty/strerror.c: In function `init_error_tables':
../../gcc-2.95.3-5/libiberty/strerror.c:546: `sys_errlist' has an incomplete
typ
e
original:
     if ((sys_errlist = (const char **) malloc (nbytes)) != NULL)
fix:
     if ((sys_errlist[eip->value] = (const char **) malloc (nbytes)) !=
NULL)
(does this need to be eip->name ?)

here's the diff
464c464
< //static const char **sys_errlist;
---
> static const char **sys_errlist;
546c546
<       if ((sys_errlist[eip->value] = (const char **) malloc (nbytes)) !=
NULL)

---
>       if ((sys_errlist = (const char **) malloc (nbytes)) != NULL)
