Problem with GNAT linking

Problem with GNAT linking

[Daniel W]

Greetings, after having spent years and years off Ada, I just the other week 
figured I'd try out some Gnat stuff. Fired up AdaGide and all examples 
worked fine. After putting it away for a week, I found that it stopped 
working. A cannot recall changing anything in the configuration after it 
worked the last time.

Below is the verbose output from gnatmake. I can understand why the linker 
is objecting. But wherefrom does gnatmake take these parameters?

Could someone please 1) see the obvious problem or 2) explain exactly how 
gnatmake (and gnatlink) generates its "ld-command"

Daniel Wengelin, a.k.a Eternally grateful (running gnat 3.15p on WinXP, with 
ADA_OBJECTS_PATH="c:\GNAT\Bindings\Win32Ada;C:\GNAT\lib\win32;C:\Program 
Files\XMLBooster\ada")

GNAT does not like long file names with spaces. 2 solutions:
- find a way to specify a shot path, eg. C:\Progra~1\XMLBoo~1\ada,
- find a way to specify arguments with double quotes, although i'm not 
sure GNAT will like this.
