Firmware build for ESPRUINOWIFI fails make: *** [libs/graphics/lcd_arraybuffer.o] Error 1

Two weeks ago I was able to build .elf and .hex files using the steps clarified by @Gordon

post #12 and #14    nRF52840DK build error: src/jslex.o make

I used this sequence:

make clean
source scripts/provision.sh ESPRUINOWIFI
make clean make
make clean && BOARD=ESPRUINOWIFI RELEASE=1 make

Which ran fine:

rgc@DESKTOP-R7T0VUC:/mnt/c/Users/robin/e­spruino$ make clean
Cleaning targets
rgc@DESKTOP-R7T0VUC:/mnt/c/Users/robin/e­spruino$ source scripts/provision.sh ESPRUINOWIFI

and on and on to completion

I have not used my PC other than for email and one Windows10 update behind the scenes did reboot my laptop this past Friday.

2021-10 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5006670)
Successfully installed on 10/19/2021

I haven't fetched (intentionally by me) or cloned from github, I haven't made any file modifications to the make, or board .py files either. I just started this morning with the intent to build continuing where I left off, but now get htis unique new error:

libs/graphics/lcd_arraybuffer.c:222:9: error: 'for' loop initial declarations are only allowed in C99 or C11 mode         for (int i=0;i<gfx->data.bpp;i+=8)
         ^

make: *** wait: No child processes.  Stop.

In the mean time I re-reading:

nRF52840DK build error: src/jslex.o make

and

https://github.com/espruino/Espruino/blo­b/master/README_Building.md#for-stm32-bo­ards-incl-espruino-board

I haven't changed any recipe within the make file, I haven't made any mods to the LCD libs, or any lib file for that matter.
