Revamp this chapter for the new profiling stuff.

Add ghcprof to file list (what about DrIFT, DtdToHaskell, Xtract and
hslibs in general?)

Substitute libexecdir, too

Add declarations so that emacs PSGML mode can find the DOCTYPE
declaration properly.

Check for litlits and dll things when making top-level constrs.

zap call to nameFromOPtr (sigh)

Get rid of debugging junk in #ifdef USE_MINIINTERPRETER :-(

Re-enable symbol table loading for BFD platforms.

Add prof to SUBDIRS

Track recent -package changes to interfaces.  Also link new symbols
blockAsyncExceptionszh_fast, unblockAsyncExceptionszh_fast,
takeMaybeMVarzh_fast.

- actually add -split-objs to SRC_HC_OPTS if $(SplitObjs) == YES and
  we're building a library.

- collect together all the $(SplitObjs) stuff in one place under
  the library building code (it's only relevant for libraries).

SplitObjs=YES should now work.

- Turn SplitObjs off.
- Update a woefully out of date comment.

Move the HC_PRE & HC_POST stuff into target.mk, so we can override
SplitObjs in the Makefile properly.

Make :r (reload) behave more like Hugs98: try and set the current module
to what it was at the last non-failing reload.

Add $(INSTALL_INCLUDES), we'll probably need it at some point.

Zap an old Partainesque .gdbinit file.

Make splitting object files the default again on non-Windoze platforms

Fixed name of std library when not building a DLL

Reduce number of warnings and raise chances of successful compilation
when *not* building an interpreter :-)

Change package name of prelude to std.

Correct an off-by-one error.

Increased paranoia.

Spell "flush" "flush" not "flish".

Set fo->bufSize even if it's 0.

Correct DLL names.

catch exceptions around commitBuffer and free the buffer.  This closes
one memory leak in the new I/O stuff, there may be another small one left.

Make PrelMain build under the new packages system (less hacky than before).

Fixed -split-objs and removed last vestiges of dLL_ifs.hi.

Removed -fcompiling-prelude flag (now removed from compiler)

Clean up the runtime heap before deleting modules (and, currently, after
every evaluation) so that the combined system can safely throw away
modules and info tables without creating dangling refs from the heap.

Change NO_MACHREGS back to NO_REGS -- I misunderstood the problem.

gcc-warning-avoiding-wibble

back off from _POSIX_C_SOURCE=199506L to 199309L, because the former
causes a bunch of extra functions thread-related to be compiled into
each module on Solaris.

msTime() uses non-POSIX features, so #define NON_POSIX_SOURCE.

uncomment prototype for msTime.

#define _POSIX_C_SOURCE 199506L
#define _ISOC9X_SOURCE

Free the spare buffers immediately we hClose a file handle.

Fix a bug in commitBuffer, and tweak the semantics of
commitBuffer/commitAndReleaseBuffer.

Add some comments on the algorithms used here.
