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 1.11, pth 2.0.7,
i586-pc-linux-gnulibc1) during gettext 0.15 build, make fails:

| /tmp/gettext-0.15>$ ./configure ; make
| [...]

| checking pthread.h presence... yes

| make[1]: *** [all] Error 2
| make[1]: Leaving directory `/tmp/gettext-0.15/gettext-runtime'
| make: *** [all-recursive] Error 1

Note that I built pth 2.0.7 with the --enable-pthread option, so there
is a pthread.h and a libpthread in /usr/local/{include,lib}. This error
is absent in gettext 0.14.4.


To get past this error, I added the --disable-threads option to gettext.
But make still failed later:

| /tmp/gettext-0.15>$ ./configure --disable-threads ; make

This error is absent in gettext 0.14.1, present in gettext 0.14.3,
0.14.4, and 0.15.


Last one: The old GNU sed 2.05 does not properly execute the script
gettext-{runtime,tools}/po/insert-header.sin: It inserts HEADER *below*
msgstr "" (instead of above msgid ""), breaking the po pseudo header.
I tried to tweak the script to suit such old sed, but did not succeed,
sorry: It seems "r" prints the file only *after* printing the current
pattern space, just before the next cycle of normal line input ("N" not
counting as normal). Noticed that while building GnuPG trunk from SVN:

| make address@hidden
| make[3]: Entering directory `/tmp/gnupg20/po'
| sed -e '/^#/d' -e 's/HEADER/address@hidden/g' ./insert-header.sin >

| make[2]: Leaving directory `/tmp/gnupg20/po'
| rm -f address@hidden && /usr/local/bin/msgfmt -c --statistics -o

| /usr/local/bin/msgfmt: address@hidden: warning: PO file header missing or

| make[1]: *** address@hidden Error 1
| make[1]: Leaving directory `/tmp/gnupg20/po'

In fact the charset indication is there, but the misplaced insertion
broke the header parsing.
