Please post your patch for the above, so we know precisely what change
you needed to make to solve your problem. If the patch looks good,
then the next step would be to post it to pgsql-patches for consideration.

Note, however, that I have never seen an error message like the above.
What is your system info?

Cygwin version
cygipc version
Windows version
CYGWIN environment variable setting
filesystem type (i.e., NTFS, FAT, etc.)

I have seen the above error message when the permissions of the following
files were incorrect:

/tmp/cygipc*
/tmp/MultiFile*

Try removing them to see if this is your problem.

BTW, I just built and tested PostgreSQL 7.2.1 under Cygwin 1.3.10. make
installcheck passed all tests.
