#3632 sdcc.exe can't compile if it's full path contains spaces.

[Roy Qu]

If sdcc is installed in a folder that has spaces in its path, like "D:\Program Files\SDCC", it can't compile and complains:

'D:\Program' 不是内部或外部命令，也不是可运行的程序
或批处理文件。
at 1: warning 190: ISO C forbids an empty translation unit
subprocess error 1

But if it is installed in "d:\sdcc", it dose compile.

[Benedikt Freisen]

This is probably very closely related to [bugs:#3616].
The apparent issue is that Windows no longer returns a sensible result for GetShortPathName(), which SDCC relies on, on drives other than C, unless you explicitly re-enable that feature.
