gcc -x bug in 2.95.3

[mbuna at undernet dot org]

I've recently upgraded gcc on my NetBSD 1.5 (release) from 
2.95.2 to 2.95.3. After wanting to recompile the kernel, this is 
not more possible using (only) gcc 2.95.3. This lasted release 
seems to have a problem when compiling FPSP assembler code for 
motorola 68040.

gcc 2.95.3 is installed with standart options, compiled with gcc 
2.95.2 then compiled again with 2.95.3. Please note that these 
errors are not happening with gcc version egcs-2.91.66 19990314 
(egcs-1.1.2 release) or the previous 2.95.2 (I actually run a 
kernel full-compiled with gcc 2.95.2).

etc.

For now, i'll use a previous version of gcc to compile these 
files, but that's an important code, and I hope you'll see 
what's wrong with this new gcc...

Thanks,
