I found a bug in compiling epoch-4.2/src/filelock.c with gcc-2.3.3 on a
NeXT:
In lisp.h is a redefinition of the macro NULL (what a bad idea!), but in the
later (over a include-chan started by #include <errno.h>) included
/usr/local/lib/gcc-lib/next/2.3.3/include/stddef.h this will be overruled
by a new define of NULL (to it's usual value).
One of the affected sourcecodelines (line 118) in filelock.c looks like:
    if (!NULL (subject_buf)
before preprocessing, and after the wrong turn:
    if (!((void *)0)  (subject_buf)
and it should be:
    if (! ((subject_buf)  == (Qnil) )
My propositions are: Change of the redifined NULL in epoch to EPOCH_NULL or
whatever and a warning-message from gnu-cpp for any redefinitions.
