pipe error on 64bit

[Marco Atzeri]

Hi,

trying to debug why recent postgresql code is failing only on
cygwin64 (all other platform and cygwin 32 are fine)

$ uname -vrm
1.7.30(0.272/5/3) 2014-05-23 10:36 x86_64

I noticed this strange output in the strace log

   102    6076 [main] pg_regress 8200 transport_layer_pipes::connect:

                      ^^^ ?

it looks a possible mismatch in the size of some variable

Suggestion ?
Marco
