I had the same problem under Solaris-2.5 (but it's not an OS bug).

I tracked it down to the change made to signames.awk, which on my
system is interpreted by mawk,

  $ mawk -Wv
  mawk 1.2.2 Jan 1996, Copyright (C) Michael D. Brennan

which generated a bogus signames.h file.

Anyway, I backed out the change (why is it necessary to escape the
`#else'?) and it worked fine.

The only thing SUNWspro's cc complains about now is stuff like:

----------------------------------------
"hashtable.c", line 233: warning: argument #1 is incompatible with prototype:
	prototype: pointer to const uchar : "./utils.pro", line 85
	argument : pointer to char
----------------------------------------

Good luck.

Hmm, it was my patch for UNICOS, that somehow has a bug in awk.

$ uname -a
kallsup kallsup 9.0.2.0 roo.2 CRAY J90
$ echo | awk '{ print "#else" }'
bad switch yylook 79

Older awks printed a literal backslash when it wasn't followed by a
"legal" character, newer awks removes the backslash.

$ uname -a
SunOS sunsite.nada.kth.se 5.4 Generic_101945-32 sun4d sparc
$ echo | awk '{ print "\z" }' 
\z
$ echo | nawk '{ print "\z" }' 
z
$ echo | gawk '{ print "\z" }'
z
