Summary0002432: libcss testsuite uses reserved identifiers
DescriptionISO C reserves identifiers beginning with __.

The libcss test suite creates a function called __assert2, which conflicts with a function in OpenBSD's assert.h, resulting in a build failure before the tests can be run:

echo " COMPILE: test/csdetect.c"
 COMPILE: test/csdetect.c
cc -MMD -MP -D_BSD_SOURCE -D_DEFAULT_SOURCE -I/usr/ports/pobj/libcss-0.6.0/libcss-0.6.0/include/ -I/usr/ports/pobj/libcss-0.6.0/libcss-0.6.0/src -Wall -W -Wundef -Wpointer-arith -Wcast-align -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Werror -O2 -pipe -g -I/include -I/usr/local/include -D_ALIGNED="__attribute__((aligned))" -DNDEBUG -std=c99 -I/usr/local/include -o build-amd64-unknown-openbsd5.9-amd64-unknown-openbsd5.9-release-lib-shared/test_csdetect.o -c test/csdetect.c
In file included from test/csdetect.c:15:
test/testutils.h:18: error: conflicting types for '__assert2'
/usr/include/assert.h:66: error: previous declaration of '__assert2' was here
test/testutils.h:22: error: conflicting types for '__assert2'
/usr/include/assert.h:66: error: previous declaration of '__assert2' was here
/usr/local/share/netsurf-buildsystem/makefiles/Makefile.top:614: recipe for target 'build-amd64-unknown-openbsd5.9-amd64-unknown-openbsd5.9-release-lib-shared/test_csdetect.o' failed
gmake: *** [build-amd64-unknown-openbsd5.9-amd64-unknown-openbsd5.9-release-lib-shared/test_csdetect.o] Error 1

The attached patch renames the function, which allows the build to continue and all tests to pass.
