Completely untested: grab the ACX_PTHREAD macro from the Autoconf Macro
Archive, then use something like this:
ACX_PTHREAD
LIBS="$PTHREAD_LIBS $LIBS"
CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
CC="$PTHREAD_CC"
AC_CHECK_SIZEOF([pthread_t], [],
[AC_INCLUDES_DEFAULT
#include <pthread.h>
])
If you don't want LIBS, CFLAGS, and CC mangled, then save and restore
their values before resp. afterwards.
Hope that helps (otherwise please report back).
Cheers,
Ralf
