Upgraded to 3.3.x and noticed that the VersionInfo resource fields
for all binaries under bin are blank (Properties->Details from
Explorer). Is this by intent or a miss?
It is breaking my application installer that relied on version check for
cygwin1.dll.
Binaries should not have VersionInfo, only cygwin1.dll had it.
Not checked on 3.3.x
Confirmed missing from cygwin.dll 3.3.0 64 and 32 bit and present up to
at least 3.2.1. Also present in some other DLLs:
cyg{asprintf,crypto,freetype,icons,iconv,lzma,ruby,ssl,unistring,usb,z}*.dll
Using SysInternals sigcheck and if you don't have that, base WMIC:
$ head /proc/version
