On Solaris 11.4.7.0.1.4.0 x86-64, the latest O/S version using patches
released by Oracle two days ago, the native compiler is /usr/bin/gcc,
version 7.3.0.  I built emacs-26.2 like this:

	set path= ( /bin )
	unsetenv CONFIG_SITE
	./configure --prefix=$prefix --with-gnutls=no --with-pop --with-gif=no && gmake all check
	...
	  CC       coding.o

Fortunately, I had already installed the Oracle Solaris Studio 12.6
compiler family in /opt/developerstudio12.6, and a build with
CC=cc got further, with some warnings:

Solaris 11 DOES have the GNU little color management system:

	% pkg info lcms2

	    Source URL: https://sourceforge.net/projects/lcms/files/lcms/2.8/lcms2-2.8.tar.gz

However, the lcms2.h header file is installed at
/usr/include/lcms/lcms2.h, rather than at top level in /usr/include.

The workaround was easy:

	gmake CFLAGS="-I${prefix}/include -I/usr/include/lcms"

A scan of several of my build farm machines showed that most do not
even have lcms2, but those that do, have it in /usr/include, EXCEPT
for some members of the Solaris family (Oracle Solaris and Hipster).

Presumably, the emacs-26.x configure.ac file could be tweaked to check
in /usr/include/lcms as well as /usr/include.
