I don't need STABS since the AST stuff in OS/Net explicitly uses DWARF
for Sun Studio, too (originally to work around an already fixed issue
but we kept it in the Makefile to avoid that we break too many
developers with older tools and have something which tests whether Sun
Studio+DWARF+CTF works).

... it seems that the gcc build handles some kind of VLAs ("variable
length arrays") - for example |char *xargv[argc+2];|
(http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/ksh/builtins/alias.c#81)
works but not |struct pollfd pollfd[bpoll_max];|
(http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libshell/common/bltins/shiocmd_solaris.c#1115).
After some experimentation I found that the following patch gets the gcc
build working again:
