make fails to build on linux

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello
trying a build.sh tools on linux I got:
/dsk/l1/misc/bouyer/HEAD/clean/src/tools/compat/../../lib/libc/regex/regcomp.c: 
In function '__regex_wctype':
/dsk/l1/misc/bouyer/HEAD/clean/src/tools/compat/../../lib/libc/regex/regcomp.c:254:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (size_t i = 0; i < __arraycount(wctypes); i++) {
    ^
/dsk/l1/misc/bouyer/HEAD/clean/src/tools/compat/../../lib/libc/regex/regcomp.c:2
54:2: note: use option -std=c99 or -std=gnu99 to compile your code

What is the right fix for this ?

For now I just moved the declaration outside of the loop
