Fix lcc compiler compile error

[xopr]

On a clean machine, I came to the discovery that make lcc failed; it gave the following set of (similar) errors:
./build/gt1.c:3840:2: error: ‘for’ loop initial declarations are only allowed in C99 mode

After research, I came to the conclusion that either Utils/lcc/src/gt1.md violates the standard on six occasions, or the makefile needed CFLAGS=-std=c11 , similar as the root Makefile.
Also, I noted that the variable was referenced incorrectly.

This pull request should fix the compiler error (tested on RHEL 7.6, GNU Make 3.82 and gcc 4.8.5

In this case, I think it's best to make it adhere to ANSI C aka C89. Because all the rest of LCC is ANSI C as well, and LCC only compiles ANSI C. What do you think?

OTOH, if it works, it works... I gooi het er gewoon in!

Bedankt!
I like the idea of a lean/old/strict/classic compiler standard, but having a shortcut is probably not bad in the case of a (binary) tool.
Maybe it's worth having a low priority improvement task for it.

It's fine. There are bigger issues with LCC to worry about. I just added a line to #70 for this.
