Thanks Robert.  Still on the subject of supporting as many compilers
as possible: why libtool treats compilers it does not know as if they
were gcc?  Let me explain: I configured a directory with CXX=como
(this is Comeau C/C++ compiler 4.3.0.1) and --disable-shared.
So I don't want shared library in this build and I am not using GCC.
Nonetheless, libtool tries to link with commands like

como -tlocal -I/usr/local/include -o intersection1 intersection1.o \
  ehandlers.o print.o  ../src/.libs/libppl.a -L/opt/como/local/lib/ \
  /usr/local/lib/libgmpxx.so -L/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.2 \
  -L/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.2/../../.. \
  /usr/local/lib/libstdc++.so 
-L/usr/local/distrib/objdir/i686-pc-linux-gnu/libstdc++-v3/src \
  -L/usr/local/distrib/objdir/i686-pc-linux-gnu/libstdc++-v3/src/.libs
  -L/usr/local/distrib/objdir/gcc -lm -lc -lgcc_s /usr/local/lib/libgmp.so
  --rpath /usr/local/lib --rpath /usr/local/lib

which refer to GCC specific options and libraries that, of course, cannot
work.  Notice that the "right" command to link would simply be

como -o intersection1 intersection1.o ehandlers.o print.o -L../src/.libs
  -lppl -L/opt/como/local/lib/ -lgmpxx -lgmp

Would it be sensible/possible to modify libtool so that, if the compiler
is not known and static libraries have to be built, a "standard" link
command is issued?  By "standard link command" I mean one that is
composed of the compiler name, one -o option, a number of .o and .a
files and the usual -Ldir and -llib options.  I guess this behavior
is likely to work with several compilers (it would work today with
Comeau and Intel compilers).
Cheers
