 Version:  3.1 and 3.2
 System: mips-sgi-irix6.5
 
 The problem
 
 Error compiling boehm-gc/mips_sgi_mach_dep.S
 
 as: Error: /usr/include/sys/regdef.h, line 17: Expected cpp-generated =
 line number
 as INTERNAL ERROR:  /usr/lib32/cmplrs/asm returned non-zero status 1
 
 
 Cause
 
 The Irix header files
   /usr/include/sys/regdef.h
   /usr/include/sgidefs.h
   /usr/include/sys/asm.h
 contain #ident "$Revision: 3.52 $" lines.
 
 The gcc cpp passess these through to the .s file, and the irix
 assembler chokes on them.  If the lines are removed from the .s
 file it can be assembled.
 
 The irix cpp removes #ident lines.
 
 
 Work around
 
 Renaming the file to .s works in this case, as irix assembler=20
 runs the irix cpp on the file by default.  This was the case for=20
 gcc-3.0.
 
 
 Proper fix
 
 Don't know.  Perhaps:
   - get gcc cpp to remove #ident lines
   - fix headers
