I have compiled the actual sources (2123) for Solaris SPARC today. I
had two things to fix in order to compile under Solaris 10:
1. unix/plugins/PseudoTTYPlugin/sqUnixPseudoTTYPlugin.c includes
"sqUnixAsynchFile.h" but this file is not in the search path.
2. unix/plugins/UUIDPlugin/sqUnixUUID.c includes <uuid.h>. I needed
to change it to include <uuid/uuid.h>.
The next thing is that "gmake install" installs the plugins under .../
lib/squeak/3.10-6/. Shouldn't that be 3.11.3?
At the moment the squeak executable cannot find the plugins and dumps
core. But that has nothing to do with the version number.
