The following packages have been uploaded to the Cygwin distribution:
* cygport-0.36.8-1
cygport is the standard method for building and maintaining packages
for the Cygwin distribution.

Add initial support for SOURCE_DATE_EPOCH
Testcase with Cygwin 3.5.0-1 src package:
- using current non-test packages including g++ 11.4.0, but
- binutils needs to be downgraded to 2.41-3 (see my related recent post
on this list)
Then this command apparently produces reproducible packages:
cd /usr/src/cygwin-3.5.0-1.src &&
SOURCE_DATE_EPOCH=1704974400 cygport ./cygwin.cygport all
This requires that always the same build directory is used. I attached
the package checksums in case someone is willing to repeat the test.
It also worked with the following of my packages, regardless of build
directory:
busybox-1.36.1-1, ddrescue-1.28-1, smartmontools-7.4-1
(busybox and smartmontools have SOURCE_DATE_EPOCH already set in the
cygport file)
