Building on Windows about lcc

[alexfru]

FWIW, as an experiment I tried compiling lcc with my own compiler (Smaller C) for Widnows. After bumping up the sizes of the internal tables/arrays in Smaller C and massaging lcc's code to exclude the features currently unsupported by Smaller C, I got it to compile and seemingly work. What I did outside of Smaller C issues is roughly:

• Compile lburg
• Run lburg on src\*.md to produce architecture-specific .c files (in reality I just did it for mips.md and removed other architectures (alpha, sparc, x86*) from src\bind.c; I also stumbled upon the missing check() function, which I defined as empty, however that's most likely wrong as it should come from dagcheck.md)
• Compile src\*.c

That was enough to make lcc compile tiny snippets of C code like the following into MIPS assembly:

int a = 4;
int inca(void) { return ++a; }

Not terribly hard.

The limits tests fails because the VC headers became too complex for LCC to handle. In this case, VAARGS for macros are present.

You cannot use any standard header anymore because of that, you should define standard functions and whatsover manually.

Plus, for VC2015 onwards, which uses the new Universal CRT, your ld on etc/win32.c should look something like:

char *ld[] = { "link", "-nologo",
        "", "-subsystem:console", "-entry:mainCRTStartup",
        "$2", "-OUT:$3", "$1", "/NODEFAULTLIB", LCCDIR "liblcc.lib", "oldnames.lib", "libcmt.lib", "legacy_stdio_definitions.lib", "libucrt.lib", "kernel32.lib", 0 };

Hope this helps anyone also trying to get this to build and work on Windows.
