Build errors on Solaris

[Tom G. Christensen]

Hi,

I tried to build a gnulib snapshot on Solaris 10 and older but there are 
currently several issues preventing the build from completing on those 
platforms.

The full buildlogs can be found here:
https://jupiterrise.com/autobuild/gnulib/

Below is an excerpt of the errors seen.

Starting with Solaris 10:
/usr/tgcware/gcc9/bin/gcc  -g -O2  -L/usr/tgcware/lib -R/usr/tgcware/lib 
-o test-getumask test-getumask.o libtests.a ../gllib/libgnu.a libtests.a 
../gllib/libgnu.a libtests.a
-lm -lm -lm -lm -lm -lm -lm -lm -lm -lm -lm
Undefined                       first referenced
 symbol                             in file
clock_gettime                       ../gllib/libgnu.a(tempname.o)
ld: fatal: symbol referencing errors. No output written to test-getumask
collect2: error: ld returned 1 exit status
make[3]: *** [test-getumask] Error 1

This issue looks to be generic. It fails similarly on CentOS 6.

There errors are repeated for test-map-c++, test-oset-c++, test-set-c++


For Solaris 9 and older which need libintl from GNU gettext there are 
these additional errors:
