Incorrect /VERSION in Makefiles

In my .pro file I have the following:
VERSION = 2.15.2.3293
DEFINES += VERSION=\\\"$$VERSION\\\"

When compiling, the makefiles for Debug and Release get the following LFLAGS entries:
LFLAGS = /DEBUG /DLL /VERSION:2.1523293

The following error occurs when linking:
LINK : fatal error LNK1147: invalid number specified with option '/VERSION:2.1523293'

It compiles (cl) using the correct correct version flag -DVERSION=\"2.15.2.3293\"

If I shorten the version number to "2.15.2.3" for example, it compiles correctly.

Please see the attached project that demonstrates the issue.

Unfortunately my project must use this build number format to comply with the coding standards of my employer.

Any advise/assistance would be most appreciated.

Thank you.
