Internal compiler error

[Lars Hecking]

 gcc version 2.95.2 19991024 (release)
 alphaev5-dec-osf4.0f (uname: OSF1 V4.0 1229 alpha alpha)
 Compiler options: -O2  -fPIC

 The problem appears when compiling tack in current releases of ncurses 5.1.
 Can't say how long this problem has really existed, as I only started
 using shared ncurses libs recently.

$ make
[...]
cd tack && make DESTDIR="" all
make[1]: Entering directory `/usr/var/tmp/ncurses-5.1/tack'
cd ../obj_s; gcc -DHAVE_CONFIG_H -I../tack -I.  -DNDEBUG -I. -I../include -I/usr/local/ncurses/include -O2  -fPIC -c ../tack/pad.c

 I have attached the preprocessed output of the source file
 (gcc -DHAVE_CONFIG_H -I../tack -I.  -DNDEBUG -I. -I../include \
  -I/usr/local/ncurses/include -O2  -fPIC -E ../tack/pad.c -o pad.i)

 Thanks!

 [I seem to have a lot more problems with gcc on this platform, esp.
  with C++. Would it be worth upgrading to a newer-than-2.95.2
  snapshot/cvs version?]
