I'm having problems with a self-built cygwin1.dll too.  Built from head
last night with -ggdb -O0, using Dave's latest gcc-4.3.4-1. Same
symptoms as Andy.

(I'm actually kinda glad you guys are seeing the problem, because my
source has one change: I replaced
with a copy of
which supports v2 relocs as well as v1. I wanted to see if it would
"just work".  If *I* was having the problem and you guys weren't, I'd
have blamed pseudo-reloc but now it looks like the problem is elsewhere.
pseudo-reloc might STILL be borked for cygwin, but...)
