Disabling PCH headers

[Robert McNulty Junior]

What is the proper format to disable PCH headers?'
I tried:
--disable-pch
--disable-pch-headers
--without-pch
--without-pch-headers


Cygwin, at moment, does not allow precompiled headers.
I'm running GCC under Cygwin.
We just recently upgraded to 1.5.0-1 cygwin
I'm running Cygwin under Windows XP pro with service pack 1a.
I'm really trying hard to build GCC. I need it for a project I'm working on
Sorry to bother you.
