Things have definitely improved. After applying sum1.diff (I'm running Fedora, which is not a Debian derivative), I was able to build gpc configured as follows:

You wrote that you are running Fedora, so I knew that. I do not know what is Fedora position concerning moving locations of system files. IIUC Debian changes were result of a proposal supposedly having wide support. I do not know if Fedora decided that they will not make the changes or if they made change preserving backwards compatibility. In the second case this may be a time bomb, some day they may decide that backwards compatibility is no longer needed.
But when running "make check", I get the following:

Cause for concern?
The above alone is no reason to worry. GCC testsuite contains a lot The above looks like test program which makes assumption about system header files which are no longer valid. GCC testsuite contains a lot of test programs, and if one of them has such problem there is no reason to worry.
More relevant for you is GPC testsuite. I do not remember if GCC 'make check' runs Pascal tests. I normally run Pascal tests chacging directory to 'gcc' subdirectory of build tree and typing
make pascal.check-long > ../chk_logg 2>&1
Note: the results take several screens so I use redirection to catch them in file. With gcc-4.x.x testsuite will fail if run immediately after build. Either install before running testsuite or copy 'libgpc.a' from libgpc build directory to gcc subdirectory and copy rts-confing.inc from libgpc build directory to gcc/p/rts subdirectory (you need to create rts subdirectiry).
I normally do the second (copy files needed to run testsuite).
