Ignore warnings during compilation of CLISP 1996-07-22 (Sun Solaris 2.4)?

[dietz@ticco.ccipe.montp.inserm.fr]

Hello,

I just have compiled CLISP 1996-07-22 on Sun Solaris 2.4 and the resulting clisp
has passed the "make test" and "make testsuite" installation steps without any
problems. However, during compilation, I have gotten lots of warning messages
like the following:

  gcc -O -W -Wswitch -Wcomment -Wpointer-arith -Wimplicit -Wreturn-type -fomit-frame-pointer -O2 -DUNIX_BINARY_DISTRIB -DDYNAMIC_FFI -c eval.c

Can I simply ignore these warnings, knowing that my compiled clisp has passed
the tests?

Is there a way to avoid these warnings?

Thank you in advance.
