[Lazarus] Can't compile a saved project

[Michael Schnell]

On Linux x86 32 Bits, using the current svn version, since two days, 
while I still can create a "new->application", after I just did "save 
project as" and saved the two files, I can't compile any more but get 
lots of error messages (seemingly when linking) starting with

Compile Project: Exit code 256, Errors:50
/usr/bin/ld: warning: link.res contains output sections; did you forget -T?
/home/mschnell/Downloads/svn/lazarus/trunk/lcl/units/i386-linux/wsimglist.o: 
In function `REGISTERCUSTOMIMAGELIST':
wsimglist.pp(262,1) Error: undefined reference to 
`WSRegisterCustomImageList'

....

What to do ?
