If you google on the error string "gcc/toplev.c:545:1: error: redefinition of ‘floor_log2’" you get amongst others a link to a link to a redhat bug report https://bugzilla.redhat.com/show_bug.cgi?id=476370 which states the fix is to use -fgnu89-inline along with the reasoning why you need to use it.
Not having tried it, I don't know if that's a good fix but it looks like something worth trying.

To compile with gcc-4.3.6 on Debian 10 I need two attached patches. First one fixes to problem above and a few other problems.
The second patch is a gross hack, to work around major breakage due to changes in Debian. Namely, Debian moved several critical files to archtecture specific subdirectories. For example, instead of
/usr/lib/crti.o
there is
/usr/lib/x86_64-linux-gnu/crti.o
(or analogous thing for different architecture). Notably, compilation of GPC is affected by location of C include files. If most C include files are in
/usr/include/x86_64-linux-gnu
then your system is affected. ATM I do not know which distributions use this scheme and which switched to Debian way. The second patch somewhat handles this issue. It is unstatisfactory, as it hardcodes 'x86_64-linux-gnu' and there is some (small ???) breakage when compiling C files (this affects mixed Pascal and C projects). Anyway, with both patches applied I can compile GPC on top of gcc-4.3.6 in Debian 10 using configure line:
../gcc-4.3.6.nn2/configure --enable-languages=c,pascal --disable-multilib --disable-mapped-location
Note that I always compile in directory separate from sources, that is reason for '../' at the start. '.nn2' suffix is to indicate that this is patched gcc (with two attached patches and gcc-4.3.5 patch).
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:
SRCDIR=../gcc-4.3.5 $SRCDIR/configure --program-suffix=-4.3.5 --disable-shared \ --enable-languages=pascal --disable-multilib \ --disable-mapped-location
But when running "make check", I get the following:

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.

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).
