	Sure does.  Thanks!

	I have now successfully built egcs 970904 on Solaris x86 2.5.1.  Some
comments/observations I have are :

-	I had problems with compiling a certain file in my current project
since the machine would start thrashing and eventually say "virtual
memory
exhausted".  I traced it to a C++ header file which had an inline member
function; moving that out of the header and into the implementation
solved
the problem.  On a better note, this project now builds without the
internal
compiler errors it has with gcc 2.7.2.2.

-	Doing make -j4 MAKE="make -j4" for the egcs build (i.e. a parallel
build)
still causes problems although it seems better than the previous
releases I
tried to build.

-	Tcl 8.0 will not build with egcs-970904 since "__ctype" is not found
by
the linker.  Tcl 8.0 compiles fine with gcc 2.7.2.2.



Thanks.
