Lassi Kortela 3dc58baa4a Include <sys/types.h> to get off_t

Lassi Kortela a6ecac95e1 Rename fs*.c -> os*.c 
I planned to put just the file system routines into these files, but
there are starting to be so many of them that I don't want to
duplicate the same set for networking, subprocesses etc.

Lassi Kortela bf11066313 Add stubs for Haiku, Minix and Solaris 2019-08-14 00:01:26 +03:00
Lassi Kortela 5ced8d91f6 Store boot image inside main executable 
Previously the boot image was kept in the separate file "flisp.boot".
This caused all kinds of problems, as bootstrapping is wont to do. The
biggest problem was finding a portable and convenient pathname for it.

Instead of dealing with all that stuff about how to find the file,
just store the image in a huge C string constant that goes into the
main executable. This necessitates adding a C-string hex dumper into
the Lisp system, and making build.sh slightly more complicated, but
that's a small price to pay for not having to carry a separate file
everywhere we go. Also, flmain.c is a lot simpler now and we don't
have to play around with symlinks.

Lassi Kortela c2da0753af Fix some more "long double" nonsense 2019-08-13 18:51:43 +03:00
Lassi Kortela 71098dd01b Fix some "long double" nonsense 
Apparently in addition to "float", "double" and "long double" there
are now standard types in <math.h> called "float_t" and "double_t".
Those types don't need to be equivalent to "float" and "double". Gah!
 2019-08-13 18:28:19 +03:00
Lassi Kortela 4a89521493 Use 'int' instead of 'char' for character variables 
MINIX libc headers define the ctype.h toupper() etc. functions as
preprocessor macros that don't cast their argument to int! So a char
argument causes clang to say "warning: array subscript is of type
'char'".

Lassi Kortela 3b13e81eae Add concept of built-in libraries and (import) statement 
R7RS syntax is: (import (library name here))

We translate this into the internal path "library/name/here". This will allow
us to easily load libraries from files later on by appending the ".sld" file
name extension.

Lassi Kortela 2ec07684d2 Get OS name from uname() 
This implies that OS names have changed. Unix-like OS names are now
capitalized. "macos" is now "Darwin". Windows is now all-lowecase "windows".
"win32" is gone. "win64" was not used in the original code despite a reference
to it.

Lassi Kortela e9d6ca265c Unify preprocessor checks for win32 
<https://sourceforge.net/p/predef/wiki/OperatingSystems/> says that _WIN32 is
always defined for both 32-bit and 64-bit versions of Windows.

Lassi Kortela 267cd00146 Remove unnecessary ifdef about unsetenv() return value 
Posix now mandates that unsetenv() must return -1 and set errno on error.
 2019-08-10 00:05:31 +03:00
Lassi Kortela 95a1c1032c Remove ifdef about memrchr() on MacOS 
MacOS doesn't have memrchr() so there was an ifdef with a custom
implementation for it. Get rid of the ifdef by always using the custom
implementation.

Lassi Kortela 1d96278313 Break down dirpath.c into fs_*.c by OS 
I much prefer this to using ifdefs. Requires a little help from the build
system but I find it worth it.
