The only way I can see is using gdb. How do you want to get
reliable information otherwise? Using Insight is somewhat
easier if you are not that familar with gdb.

I can. The current bash in latest is a native build in a
Cygwin environment created by setup.exe. gcc-2.95.2-6, cygwin
1.1.8 (currently 1.3.0). I'm using the following config script:

======= SNIP ========
#!/bin/sh

#DEBUG=echo

SRCDIR=../src

HOST=i686-pc-cygwin
BUILD=${HOST}
TARGET=i686-pc-cygwin

PREFIX=/usr
EXECPREFIX=${PREFIX}
BINDIR=/bin
SYSCONFDIR=/etc
LIBEXECDIR=${EXECPREFIX}/sbin

OPTS=--enable-haifa

${DEBUG} ${SRCDIR}/configure \
        ${OPTS} \

This is the spawn_guts function, called by some exec(2) call
