egcs-971201 build on SunOS 5.5.1

[Johann Petrak <johann@ai.univie.ac.at>]

I tried to build egcs-971201 on a SunOS 5.5.1, 
Generic sun4u sparc SUNW,Ultra-2 machine,
using gnumake version 3.74 and gcc 2.7.2.1:
  cd objsolaris
  $EGCS/configure --prefix $pref
  gnumake bootstrap-lean

[...]
make[2]: Entering directory `/oberlaa/src/egcs-971201/OBJ-solaris/gcc'

make[2]: *** [enquire.o] Error 1

I had no propblems compiling on a SunOS 4.1.3_U1 2 sun4m
machine.

(The 1127 snapshot didnt compile on SunOS 5.5.1 either)

Any ideas? 

Excuse me (but let me know) if this is not the right list
for this kind of questions!

Cheers,
  Johann
