Building gnulib (vasnprintf.c) on this platform (Mac OS X 10.4 fully updated) results in:
/usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: Undefined symbols: _signbitl collect2: ld returned 1 exit status Configure finds this: configure:79962: checking for signbit macro configure:80053: gcc -std=gnu99 -o conftest -g -O2 -I/opt/local/include conftest.c -lm >&5 configure:80056: $? = 0 configure:80062: ./conftest configure:80065: $? = 0 configure:80082: result: yes configure:80084: checking for signbit compiler built-ins configure:80169: gcc -std=gnu99 -o conftest -g -O2 -I/opt/local/include conftest.c -lm >&5 configure:80172: $? = 0 configure:80178: ./conftest configure:80181: $? = 0 configure:80198: result: yes However, apparently, it doesn't work out well. The system does appear to have __signbit? in its libc. Ideas? /Simon
