Subject: build failure: aicasm: renamed yaccage

Hi!
My randconfig builds notoriously fail on this:

[~/linux/drivers/scsi/aic7xxx/aicasm](vanilla)$ make -j1
bison -d -b aicasm_gram aicasm_gram.y
mv aicasm_gram.tab.c .//aicasm_gram.c
mv aicasm_gram.tab.h .//aicasm_gram.h
bison -d -b aicasm_macro_gram -p mm aicasm_macro_gram.y
mv aicasm_macro_gram.tab.c .//aicasm_macro_gram.c
mv aicasm_macro_gram.tab.h .//aicasm_macro_gram.h
flex  -o aicasm_scan.c aicasm_scan.l
flex  -Pmm -o aicasm_macro_scan.c aicasm_macro_scan.l
cc -I/usr/include -I. -I./ aicasm.c aicasm_symbol.c .//aicasm_gram.c .//aicasm_macro_gram.c .//aicasm_scan.c .//aicasm_macro_scan.c -o .//aicasm -ldb
aicasm_symbol.c: In function ‘aic_print_reg_dump_end’:
aicasm_symbol.c:393:13: warning: implicit declaration of function ‘tolower’ [-Wimplicit-function-declaration]
  393 |   *letter = tolower(*letter);
      |             ^~~~~~~
aicasm_gram.tab.c:204:10: fatal error: aicasm_gram.tab.h: No such file or directory
compilation terminated.
aicasm_macro_gram.tab.c:167:10: fatal error: aicasm_macro_gram.tab.h: No such file or directory
compilation terminated.

And the generated yaccage has:
#include "aicasm_gram.tab.h"
which tries to refer to the just renamed file.

As the files in question are generated, with the filename coming from $YACC
rather than source, it'd take some after-processing with sed or a similar
hack.  Thus, instead of sending a patch, I thought it'd better to ask:
what the renames are for?


Meow!
