-## Can't use Sun Studio with shared libs:
-##  * non-redistributable libs in /opt/SUNWspro prevent Sun Studio
-## Can't use GCC4
-##  * C++ is way broken for 32-bit Sparc

+## Add GCC4 lib dir to CFLAGS and friends because gcc3core_rt puts it's 
+## libgcc_s.so in /opt/csw/lib and this breaks the build in all sorts of weird 
+## places.
+## Rationale: Automake keeps wanting to put /opt/csw/lib in the front of the 
+## -L options during the linking phase, so the GCC3 libgcc_s gets pulled in 
+## first and an unresolved symbol error occurs. By adding to the 
+## CFLAGS/FFLAGS/FCFLAGS/CXXFLAGS, it is pulled in before AM_LDFLAGS in the 
+## linking stage in most automake-generated Makefiles. Ugly hack but it works.
+##
+## Adding -dalign to *FLAGS in attempt to fix bus error in nf_test/ftst_vars4
+## in fuction nf_put_vlen_element
