1.5.2 ltdl.c: parse error

[Rupert Mazzucco]

I get an error when trying to compile 1.5.2 in the gcc-3.3.3 tree
together with other GNU tools as part of make bootstrap.  This happens
at or after stage2.  I can build 1.5.2 by itself and it passes make check.

In an attempt to fix the problem myself I removed five or so linefeed
(ctrl+l) chars that I found in ltdl.c, but to no avail.

System:
  Linux 2.6.3, glibc 2.3.2
Host tools:
  gcc 3.3, binutils 2.13.1, libtool 1.4.3, make 3.80, autoconf 2.58
Linked into gcc 3.3.3 tree:
  autoconf 2.59, automake 1.8.2, binutils 2.14, bison 1.875, gdb 6.0,
  libtool 1.5.2

Configured in separate build-gcc/ with:
  ../gcc-3.3.3/configure --prefix=/opt/gcc-3.3.3 --with-cpu=pentium3
  --enable-threads --enable-target-optspace --disable-multilib
  --enable-languages=c,c++,f77 --disable-nls

Compile attempt with:
  make CFLAGS='-Os' LIBCFLAGS='-O2' LIBCXXFLAGS='-O2\
   -fno-implicit-templates' bootstrap
