gpc --version
is not coherent among different versions of gpc, i.e. they do not provide me with output that is comparable to each other. I have access to one gpc installation that is on a sparc system. It gives me the output:
gpc --version 2.8.1
This is a very laconic output compared to the one I get on my cygwin version (I was installing a binary distribution):
gpc --version gpc 20030323, based on gcc-3.2.2 Copyright (C) 1987-2003 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
This output also reveals that gpc is based on gcc. However, I thought gpc was a freestanding compiler that did not precompile anything (according to "The GNU Pascal Manual", which is something I was able to get in PDF). Is it based on gcc or not?
Now on the 2.8.1 system, I have problems compiling source that uses the extension "external" in combination with a "name" directive like this:
procedure foo; external name 'foo';
I have to keep it like this instead:
procedure foo; external;
However, this means that I come in trouble when I want to compile source that some people have made.
My questions are:
How is the version system working with gpc? Which is the latest stable gpc and does it use the "extern name 'foo'" extension? Which is the latest unstable gpc? How unstable is it? Is there a switch to actually enable "extern name 'foo' in all versions?
Thanks a lot for your attention, and I also want to thank the people that already have helped me on this list.
