[Bug c/42091] New: -imacros option does not work on gcc 4.2.1 scratchbox

[frederic dot chifflet-nonst at stericsson dot com]

I use Scratchbox on an Ubuntu 8.04 OS with ARM target. The gcc version used in
the scratchbox is 4.2.1.

I modified the gcc.specs file, I add -imacros option to cpp. 
Compilation don't even sart, I have a fatal error.

If I add to cpp the compilation switches -DTOTO1 -DTOTO2 instead -imacros, the
compilation is OK.

But I have to use -imacros option, in the near future the project I work on
will have thousands of switches.

Does someone have a clue on this issue ? 

Thank you !
