Sure it will. Please note that this is not the most specific
reference; you are propably referring to ISO/IEC 9899:1990. GCC will
accept programs written in this language; it will reject all others
and stick to a strict interpretation of the standard if invoked as
'gcc -ansi -pedantic'.

Recently, the standard has been revised; the official version now is
ISO/IEC 9899:1999. GCC supports a number of new features of that
standard, see http://gcc.gnu.org/c9xstatus.html for details. GCC
continues to support standard C programs which don't use any of the
new features.
