This can cause problems if you observe the output of the compiler to
detect failures. Invoking @samp{cc -c a.c -o a.o; cc -c b.c -o b.o; cc
a.o b.o -o c} solves the issue.
@item Don't rely on correct @code{#line} support
On Solaris 2.8, @command{c89} (Sun WorkShop 6 update 2 C 5.3 Patch
111679-08 2002/05/09)) rejects @code{#line} directives whose line
numbers are greater than 32767. In addition, nothing in @sc{posix}
makes this invalid. That is the reason why Autoconf stopped issuing
@code{#line} directives.
