I committed this as pascal language maintainer. For gpc mailing list mainly: I had to add to XFAIL for gpc because of the buggy line information. I used an old gpc gpc 20050331, based on gcc-3.4.4 (cygming special, gdc 0.12, using dmd 0.125) but this is the official cygwin distro of gpc. Do newer gpc binaries give better results?
