build problems on old Linux libc5

[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, libiconv 1.12, pth 2.0.7,
i586-pc-linux-gnulibc1) during gettext 0.17 build, make check fails
four tests:

| $ ./configure --disable-threads
| [...]
| checking for snprintf... yes
| checking for vsnprintf... yes
| checking for wcwidth... no
| [...]
| $ make check
| [...]
| FAIL: test-c-strcase.sh
| test-snprintf.c:61: assertion failed
| FAIL: test-snprintf
| test-vsnprintf.c:74: assertion failed
| FAIL: test-vsnprintf
| test-wcwidth.c:45: assertion failed
| FAIL: test-wcwidth


BTW ./configure of 0.17 fails to detect long longs, which do work (and
were correctly detected by gettext 0.16.1):

| checking for unsigned long long int... no
| checking for long long int... no

That seemingly is due to the preprocessor not able to compare long longs
constants, as shown by config.log:

| configure:26110: checking for long long int
| configure:26160: gcc -o conftest -g -O2   conftest.c  >&5
| conftest.c:57: two `l's in integer constant
| conftest.c:60: two `l's in integer constant
| configure:26166: $? = 1

Where lines 57 and 60 are:

|       #if ! (-9223372036854775807LL < 0 && 0 < 9223372036854775807ll)
|       #if ! (18446744073709551615ULL <= -1ull)

Without these preprocessor 6 lines block, the test for long long
compiles and succeeds.


Alain.
