What precisely does "for ages" mean?
Note you can use the "-v" option to make rebaseall verbose. Maybe this
will help you debug.

FWIW, we have the following:
$ fgrep 13L /usr/include/w32api/winerror.h | head -1
#define ERROR_INVALID_DATA 13L
It seems like rebase cannot handle 64-bit DLLs?

If you install all Cygwin packages, then you will likely run out of
rebase address space.

rebase will skip some errors (e.g., when a DLL is not writable), but
will exit if FixImage() fails. Maybe rebase should skip this error too?

rebaseall uses the former approach. It creates a list of files to
rebase from setup.exe's "package database" and an optional user supplied
file list. From the rebaseall script, we have the following:
# Create rebase list
find /etc/setup -name '*.lst.gz' | xargs gzip -d -c |
grep -E "\.($Suffixes)\$" |
sed -e '/cygwin1\.dll$/d' -e '/cyglsa.*\.dll$/d' -e 's/^/\//' >"$TmpFile"
# Append user supplied file list, if any
if [ -n "$FileList" ]
cat "$FileList" >>"$TmpFile"
