I build a lot of software on Solaris 10 and 11, and have seen similar
complaints many times.  Here are the configure script settings
that I use that appear to fix them (at least sometimes):

### This version is for Solaris 10.  /usr/include/sys/feature_tests.h
### says
###	 * It is invalid to compile an XPG3, XPG4, XPG4v2, or XPG5 application
###	 * using c99.  The same is true for POSIX.1-1990, POSIX.2-1992, POSIX.1b,
###	 * and POSIX.1c applications. Likewise, it is invalid to compile an XPG6
###	 * or a POSIX.1-2001 application with anything other than a c99 or later
###	 * compiler.  Therefore, we force an error in both cases.
### However, it is permitted to use XPG6, so we do that

CC=/opt/sunstudio12.1/bin/c99
CFLAGS="-I/usr/local/include -D_XOPEN_SOURCE=600 -D_XPG6"
CXX=/opt/sunstudio12.1/bin/CC
CXXFLAGS="-I/usr/local/include -D_XOPEN_SOURCE=600 -D_XPG6"
LDFLAGS="-R/usr/local/lib -L/usr/local/lib"

Try

	% man standards

on Solaris 10 or 11 to see how Sun tried to cope with the
myriad of C and POSIX and XPG standards.
