Guile 1.8.4 build difficulties on old Linux

[Alain Guibert]

Hello gentlemen,

On my old Linux box (Intel Pentium 200 MMX, Debian Bo 1.3.1,
kernel 2.0.40, gcc 2.7.2.1, libc 5.4.33, GNU ld cygnus-2.7.1,
libiconv 1.12, pth 2.0.7, gettext 0.17, i586-pc-linux-gnulibc1,
autoconf 2.62, fileutils 3.16, Make 3.75, bash 2.0.0(1)), gmp 4.2.2,
there were some difficulties while building guile 1.8.4:

| $ ./configure
| [...]
| checking for __gmpz_init in -lgmp... no
| configure: error: GNU MP not found, see README

Indeed this distribution has its original old gmp 2.0.2 as
/usr/lib/libgmp.so.2.0.2, which has no __gmpz_init (but a mpz_init).
The gmp 4.2.2 built from source as /usr/local/lib/libgmp.so.3.4.2 is not
checked automatically. Problem workaround by presetting LDFLAGS.

Line 194 of pthread.h (of Gnu PTH 2.0.7) is "typedef int socklen_t;",
the platform doesn't have socklen_t otherwise. Problem workaround by
--disable-error-on-warning.

Line 320 of libguile/read.c ends by two semi-colons, the attached
bug-double-semicolon.patch should fix it.


At this stage Guile builds and passes the tests succesfully. However
there is an incompatibility between --without-threads and "make check":

| $ LDFLAGS="-L/usr/local/lib" ./configure --disable-error-on-warning 
--without-threads
| $ make
| $ make check
