The GNU Pascal Compiler (GPC) is, as the name says, the Pascal compiler of the GNU family. This means:
GPC is a 32/64 bit compiler,
does not have limits like the 64 kB or 640 kB limit known from certain operating systems – even on those systems –,
runs on all operating systems supported by GNU C nd more (note: the runtime system only supports ASCII based systems; that includes almost all of today's systems, but a few IBM machines still use EBCDIC; on those, the compiler might run, but the runtime support might need major changes),
can act as a native or as a cross compiler between all supported systems,
produces highly optimized code for all these systems,
is Free Software, is compatible to other GNU languages and tools such as GNU C and the GNU debugger.
