Re: GNUstep Make not adding -fblocks

[David Chisnall]

I am no good at autoconf, but as a simple test, you can try this file:

void(^block)(void) = ^(void) {};

$(CC) -c block.c

This may Just Work™ - it will on OS X with both clang and Apple gcc.  If so, 
that's great.  If not (exit code from the compiler is not 0), then try:

$(CC) -c block.c -fblocks

If this works, then add -fblocks to CFLAGS and OBJCFLAGS (and maybe CXXFLAGS).

Did you take a look at the exception test I sent you a mail about?  It seems 
that the configure script is testing whether exceptions work, then deciding 
that, even though they do, it won't let you use them because it doesn't like 
the version of GCC that you have.
