Breaks compilation of other backends

[spth]

I tried to compile this fork of sdcc on my Debain GNU/Linux testing system. However, it seems the changes break the non-stm-backends. I had to use the workaround of disabling most non-stm8 ports:

./configure --disable-z80-port --disable-z180-port --disable-gbz80-port --disable-ez80_z80-port --disable-r2k-port --disable-r3ka-port --disable-tlcs90-port --disable-ds390-port --disable-mcs51-port --disable-ds400-port

The z80-related backends don't compile:

gcc -pipe -ggdb -g -Og -Wall -Wno-parentheses -I./.. -I.. -I. -I../.. -I./../../support/util -I.  -c -o main.o main.c
main.c: In function ‘do_pragma’:

The ds390 library doesn't compile:

../../bin/sdcc -I../../device/include -I../../device/include/mcs51 -mds390 --nostdinc --std-c11 -c rand.c -o ds390/rand.rel

The mcs51 library doesn't compile:

The ds400 library doesn't compile:

ds400/rand.asm:60: Error: <q> missing or improper operators, terminators, or delimiters

The pdk13, pdk14 and pdk15 libraries also fail to compile (but for some reason this does not stop the build process).

Building issues have been solved on commit cf1d3ae. However, I noticed all autoconf/aclocal/automake files are expecting automake version 2.64. This breaks the compilation process on my computer, where I am using automake 2.69. However, there is no reason why it should be fixed to a specific version as I could modify this restriction manually with no consequences.
@spth : why is automake version limited only to 2.64? Could we fix this so any version >= 2.64 is supported?

[spth]

Thanks. I can confirm that SDCC compiles for me now with all ports enabled.

I am not that familiar with the build system, so I don't know why automake 2.64 was required. I guess it once really was required, but subsequent changes might have made this requiremetn obsolete.

However, there are still errors compiling the pdk15 library (and I see similar errors when trying to compile the pdk15 regression tests):

philipp@notebook5:/tmp/sdcc-gas/device/lib/pdk15$ make
../../../bin/sdcc -mpdk15 -I./../../include -I. --std-c11 -c ../time.c
