Same here (Linux). To catch the errors as OSX does, I use for years

MYCFLAGS="-g -Wall -Werror-implicit-function-declaration -fno-common"
MYCXXFLAGS="-g -Wall"
MYLDFLAGS="-Wl,--no-undefined"


LDFLAGS="$MYLDFLAGS" CFLAGS="$MYCFLAGS" CXXFLAGS="$MYCXXFLAGS" ./configure \
...

so:

Susequently, a set of modules naturally won't be compiled.
