GnuPG 1.9.92 build failures on old Linux

[Alain Guibert]

Hello,

On my old Linux box (Intel Pentium 200 MMX, Debian bo, kernel 2.0.40,
gcc 2.7.2.1, libc 5.4.33, GNU ld cygnus-2.7.1, pth 2.0.7) during
GnuPG 1.9.92 build, make fails:

| $ ./configure; make

I disabled agent for now. But I still failed:

| $ ./configure --disable-agent; make

| make[1]: *** [all-recursive] Error 1
| make[1]: Leaving directory `/tmp/gnupg-1.9.92'
| make: *** [all] Error 2

My system /usr/include/unistd.h line 656 is:

| extern void   usleep __P((unsigned long __usec));

While libpth 2.0.7 /usr/local/include/pth.h contains:

| extern int            pth_usleep(unsigned int);
| #define usleep        pth_usleep


I temporarily commented out the unistd.h usleep to get past this error.
But I still failed later:

| gcc -DHAVE_CONFIG_H -I. -I. -I..  -I../gl -I../intl -I../common -DLOCALEDIR=\"/usr/local/share/locale\" -DGNUPG_BINDIR="\"/usr/local/bin\"" -DGNUPG_LIBEXECDIR="\"/usr/local/libexec\"" -DGNUPG_LIBDIR="\"/usr/local/lib/gnupg\"" -DGNUPG_DATADIR="\"/usr/local/share/gnupg\"" -DGNUPG_SYSCONFDIR="\"/usr/local/etc/gnupg\""       -I/usr/local/include  -I/usr/local/include -I/usr/local/include -I/usr/local/include -g -O2 -Wall -c watchgnupg.c

| make: *** [all] Error 2

So I replaced socklen_t by int in watchgnupg.c, and this time build
succeeded. Make check passed all PGP tests OK, but failed the 2 gpgsm
tests:

| asschk: cmd_expect_ok: expected OK but got `ERR 50331649 General error <GpgSM>'
| FAIL: sm-sign+verify
