(Windows) GPU detection fails when started from command line

[RichardHaselgrove]

Previous reference https://lists.ssl.berkeley.edu/pipermail/boinc_alpha/2017-July/021908.html

If the client is started from the Windows command line with

prompt>boinc --detach_console

GPU detection fails, and any previous coproc_info.xml file is deleted.

Starting the client with

prompt>boinc.exe --detach_console

allows GPUs to be detected and used as normal.

Changing the commandLine used in

https://github.com/BOINC/boinc/blob/master/client/main.cpp#L488

to use an explicit .exe extension also solves the problem - as was found by the author of https://github.com/BOINC/boinc/blob/master/client/gpu_detect.cpp#L640 (though I prefer the idea of passing the command line here too, rather than hard-coding the executable name)

Tests reconfirmed with code as at the v7.8.1 tag.

Is PR #2036 a fix for this problem?

Seeing how PR#2036 was added to Master, I updated my local repository and built a new client and manager from Master. Then ran those from the command line, with boinc --detach_console, and got this:

Oops - still broken in v7.9.0 oops again, forgot I'd reverted to v7.8.3 after previous test. v7.9.0 (master clone 30 Jan 2018) is OK: launching with 'boinc' generates

01/02/2018 12:12:58 |  | [coproc] launching child process at boinc.exe
01/02/2018 12:12:58 |  | [coproc] relative to directory D:\BOINC
01/02/2018 12:12:58 |  | [coproc] with data directory "D:\BOINCdata"

and GPU detection works. Launch with 'boinc.exe' also good.

Retested for confirmation with v7.12.1: solution working correctly. Closing / complete
