Thanks. But for some reason it's not getting picked up: gcc -c -I. -I/usr/local/include -I/home/reynolds-gregg/include -I/usr/local/include -DNDEBUG -D_GNU_SOURCE=1 -D_REENTRANT -D__EXTENSIONS__ -D_TC_PREFIX="\"/usr/local\"" -D_TC_INCLUDEDIR="\"/usr/local/include\"" -D_TC_LIBDIR="\"/usr/local/lib\"" -D_TC_BINDIR="\"/usr/local/bin\"" -D_TC_LIBEXECDIR="\"/usr/local/libexec\"" -D_TC_APPINC="\"-I/usr/local/include\"" -D_TC_APPLIBS="\"-L/usr/local/lib -ltokyocabinet -lbz2 -lz -lpthread -lm -lc \"" -I/usr/include -std=c99 -Wall -fPIC -fsigned-char -O2 tcutil.c result: tcutil.c:4948: warning: implicit declaration of function `isnormal' and then tcutil.o:tcutil.c:(.text+0x2889): undefined reference to `_isnormal' If I run cpp -dDI tcutil.c it shows the macro included and substituted properly. I can't see anything in the source that would account for this.
