Compiling source code gives lots of messages on unguarded ifs and while??

[msetzerii]

Have a user that booted my project that uses grub4dos UEFI. It displays the background image but doesn't then display any of them menu options and keyboard seems to be totally dead.

Download the source code, since I was just using binary. Did the configure and make and it comes up with lots of messages about unguarded if's and while's. First few seemed obvious with just space and tab differences, but the third one isn't. line 4453 of builtins.c looks like if followed with next line with ; at end, but then next lines stay at the indented position.

Seen some issues with various versions of compiler to build programs. Make ends with

collect2: error: ld returned 1 exit status make[2]: [Makefile:612: pre_stage2.exec] Error 1 make[2]: Leaving directory '/home/msetzerii/Downloads/grub4dos-for_UEFI/stage2' make[1]: [Makefile:373: all-recursive] Error 1 make[1]: Leaving directory '/home/msetzerii/Downloads/grub4dos-for_UEFI' make: *** [Makefile:313: all] Error 2

Look at some of the code, and it appeared that was obvious where the code falls, but others had the spacing/tabs all over the place, so I could figure which way the compiler would do it. Seems going to an older compiler that doesn't check things? Is there a reason why these are reported by the newer compiler but not the older? Well, beyond my knowledge for a program like this. Just it usually works. Just had a user that couldn't get the grub4dos efi to work on his system that works on mine. Gave him instructions to use the regular grub4dos and believe it worked on his system. Was just looking if it might be something in code I could see. Had another user that got new Dell machines that no longer included BIOS boot option, so had to make an EFI boot option and grub4dos works. Thanks for your time.
