Invalid preprocessing directives in "gthr.h"

[Edward Duffy]

Hi,

  This is my first time compiling GCC, and I've got some errors during the
"make bootstrap" after about an hour or
some of compilation.  I'm compiling on "i686-pc-linux-gnu", kernel version
2.4.3-20mdk (Mandrake).

The error is -

In file included from
../../../../gcc-3.0/libstdc++-v3/libsupc++/eh_alloc.cc:39:
../include/bits/gthr.h:29:2: invalid preprocessing directive

gmake[2]: *** [eh_alloc.lo] Error 1

which ends up causing 3 more errors right after that.  Is there some option
I should enable with
the "make bootstrap"?

 Thank you,
