According to Clyde Meli:

...

/usr/local/lib/gcc-lib/sparc-sun-solaris2.5.1/2.7.2.3/include/unistd.h:230: conf licting types for `rename' /usr/local/lib/gcc-lib/sparc-sun-solaris2.5.1/2.7.2.3/include/stdio.h:161: previ ous declaration of `rename'

It seems as if the (AutoConf) configuration script did not recognize your system correctly. Please try and edit `gpc-config.h' manually and flip the `HAVE_UNISTD_H' switch.

Good luck,

Dipl.-Phys. Peter Gerwinski, Essen, Germany, free physicist and programmer peter.gerwinski@uni-essen.de - http://home.pages.de/~peter.gerwinski/ [971005] maintainer GNU Pascal [971001] - http://home.pages.de/~gnu-pascal/ [971005]

I found what was confusing AUTOCONF - I did not set the CC environment variable (I never did and I never had problems :) ) to /usr/local/bin/gcc (or wherever gcc is located). I recompiled the C compiler now using the precompiled gcc 2.7.2.1 package available on the net.

Now I attempted to compile the beta but I ran into problems again, this time with parse.y (I've recompiled bison again - version 1.25 - from what I tried to check I found it should be the latest version) and using the new parse.h which you gave me. Now I got the following errors:
