PATH_MAX missing cross building gmon-sol2.c

PATH_MAX missing cross building gmon-sol2.c

[Jay]

I am crossing from i686-cygwin to sparc-solaris (my Sun cc won't compile gcc
due to macros with empty parameters like in c-common.c):

/src/gcc-4.3.1/gcc/config/sparc/gmon-sol2.c: In function '_mcleanup':
/src/gcc-4.3.1/gcc/config/sparc/gmon-sol2.c:182: error: 'PATH_MAX' undeclared (first use in this function)
/src/gcc-4.3.1/gcc/config/sparc/gmon-sol2.c:182: error: (Each undeclared identifier is reported only once
/src/gcc-4.3.1/gcc/config/sparc/gmon-sol2.c:182: error: for each function it appears in.)
/src/gcc-4.3.1/gcc/config/sparc/gmon-sol2.c:182: warning: unused variable 'buf'

make[3]: Leaving directory `/cygdrive/d/obj/cross-gcc/gcc'

Could be my /usr/local/sparc-solaris/include is old.

just add #define PATH_MAX 1024

I deliberately didn't put #ifndef in so that if it is defined, and this mismatches, will error.

Thanks,

Or a configuration problem, see PR target/28097.
