Failure to bootstrap gcc 20021015 cvs trunk on cygwin: SIGSEGV gengtype.c:376: rtx_next[i] = -1;

[Christian Jönsson]

This was on a Windows XP SP1/cygwin P4 system with these packages:

binutils  20020706-2
cygwin    1.3.12-4
dejagnu   1.4.3       (cygwin ver. 20010117-1 with 1.4.3 on top)
gcc       3.2-1

In-tree joined gcc and binutils cvs trunks.
