The following two programs fail on i386-apple-darwin when using gpc version 20051116 with gcc-3.4.5, but not when using gpc version 20070904 with gcc-4.1.2. This was reported by Stéphane Nicolet on the mac-pascal mailiong list. Does someone remember if this is a back-end or front-end problem ?
{$mac-pascal} program modbug; var a,b: integer; c: boolean; begin a := 22; b := 12; c:= ((a - 15) mod b) = (b-1) end.
{$borland-pascal} program modbug; var a,b: integer; c: boolean; begin a := 22; b := 12; c:= ((a - 15) mod b) = (b-1) end.

I'll add to Ardiaan's failing compiler list with powerpc-apple- darwin8 with gpc version 20051116, based on gcc-3.4.5 and gpc version 20060325, based on gcc-3.4.5.
Also got the same non-failure result as Adriaan did with gpc version 20070904, based on gcc-4.1.2 with powerpc-apple-darwin8.
Details are below.

FYI,
With this program I get the same compilation error on SUN Sparc Solaris 10 and a different error on x86 Linux (Debian), with two different versions of gpc. See details below. Also if I remove the {$mac-pascal} directive the program compiles and gives the expected result.
SUN Sparc Solaris 10:
