[Lutz]

The aliasing  warnings are ok and also have to be suppressed on AIX, BSD, Linux and on some more. Put -fno-strict-aliasing into the gcc line.



For the ISO_C90 warning add SUNOS in line 41 of newlisp.h:

#if defined(CYGWN) || defined(OS2) || defined(SOLARIS) || defined(AIX) || defined(SUNOS)

... or perhaps you should try makefile_opensolaris instead of makefile_sunos

I added -fno-strict-aliasing to CFLAGS and updated line 41 in newlisp.h.

I was able to compile successfully and test without any of those warnings.

Thank you
