../libgnu/stdio.h:1252:18: error: expected constructor, destructor, or type conversion before '(' token

See the attached for more details. I assume I've done something wrong.
I have a directory "./gui" that holds the sources for the gui branch, and a second directory, "./gui_build" where I intended to build the sources. From the build directory, I tried "../gui/configure ..."
This looks like some pre-processor error, like a symbol being unexpectedly defined, or not. I would advise to run compile command (just copy and paste in a terminal) with the -E flag and inspect the pre-processed results at the lines corresponding to the first error (../libgnu/signal.h, line 168). According to the log file you attached, the command to run should look like (not tested):
/opt/local/bin/gcc-mp-4.5 -DHAVE_CONFIG_H -I. -I../../gui/libcruft -I.. -I../libgnu -I../../gui/libgnu -D_THREAD_SAFE -pthread -I/opt/local/include -pipe -O0 -g -m64 -ggdb3 -gstabs -D_THREAD_SAFE -pthread -funroll-loops -lstdc++ -D_THREAD_SAFE -pthread -Wall -W -Wshadow -Wformat -Wpointer-arith -Wmissing-prototypes -Wstrict-prototypes -Wwrite-strings -Wcast-align -Wcast-qual -pipe -O0 -g -m64 -ggdb3 -gstabs -D_THREAD_SAFE -pthread -funroll-loops -lstdc++ -D_THREAD_SAFE -pthread -MT misc/libcruft_la-lo-error.lo -MD -MP -MF misc/.deps/libcruft_la-lo-error.Tpo -c ../../gui/libcruft/misc/lo-error.c -fno-common -DPIC -E -o lo-error-cpp.c
the result being saved in lo-error-cpp.c.
